Digital Micro Vickers Hardness Testing System: Everything You Need to Know

Digital micro Vickers hardness testing system is a common way of quantifying the hardness of materials in engineering and manufacturing. This is accomplished by using a sharp object such as a diamond point or needle to scratch the surface of the material being tested in order to determine how much force is required for scratching it. In recent years there have been advancements in technology that make this process faster and more accurate while maintaining high precision for hardness measurements.

Digital micro Vickers hardness testing system-based equipment generally falls under two categories: a contact type, which touches the test material, and a non-contact type that does not touch the sample. The noncontact microhardness testers are generally more accurate. Contact instruments require the user to apply just enough force to make contact with the surface of the object being tested. With non-contact instruments, it is possible to press harder on an object that has a lower hardness level than another with a higher hardness level without contacting it. A force is applied using a Vickers indenter or diamond tip that is quite small in size. An indenter tip that looks like this can have different shapes and sizes depending on its purpose.

Most digital micro Vickers hardness testing systems measure the force required to indent or scratch the material surface. Vickers indenters are a special type of diamond tip used to measure the hardness of materials. A Vickers indenter, also known as a digital microhardness tester, applies an extremely small amount of power (generally less than 1 V) and simultaneously touches the test surface with its diamond tip to achieve indents. A Vickers Indenter measures hardness in units called Vickers Units (VU). Each VU has a numerical value ranging from 0 to about 1000000. An instrument that gives readings in VU is called a digital micro Vickers hardness tester and another instrument that gives readings in grams is known as a digital micro-hardness tester.

In a digital MHL system, an integrated circuit chip is used for each measuring step. A very high-precision (100 nm) diamond tip probe generates the electrical signal which is amplified by an integrated circuit and transmitted to the display unit. At the display unit, the signal is digitized and recorded to a logarithmic scale. The data is then transmitted to a PC where it can be interpreted and displayed as the hardness value on screen. Some MHL systems also have an integrated sensor that measures the pressure applied by the diamond tip to a sample and transmits it to a PC as well.

In order for the digital micro Vickers hardness testing system to function properly and produce accurate results, all of these components must be in good working order. It's crucial that the tips are cleaned before each use. Vickers tips can be cleaned with alcohol or acetone and left overnight without any ill effects (depending on quality of the tip). Diamond tips and probes can be cleaned with alcohol or acetone as well.

The instrument is then calibrated for the first time. Calibration should be performed with both the tip and the sample holder to ensure accuracy. Calibration should be done at least every 50 readings. Proper maintenance is essential to ensure proper functioning of a digital micro-hardness tester or digital micro Vickers hardness testing system. It is important that these instruments are properly cleaned between each use and stored safely to avoid damage from temperature, humidity or other factors which could cause damage to parts within the instrument. This may also require lubrication on parts such as needle probes that will come into contact with samples in order for them to function properly.

Microstructure and properties of Ti/TiBCN coating on 7075 aluminum alloy by laser cladding

Publication date: 25 January 2018 Source:Surface and Coatings Technology, Volume 334 Author(s): Yuxin Li, Pengfei Zhang, Peikang Bai, Liyun Wu, Bin Liu, Zhanyong Zhao Ti/TiBCN coatings were fabricated on the 7075 aluminum alloy by laser cladding. The influence of TiBCN content on microstructure, micro-hardness, electrochemical corrosion and wear resistance of the cladding coatings were studied by SEM, XRD, Vickers micro-hardness tester, a typical three-electrode electrochemical workstation and straight-line-reciprocating dry sliding wear tester, respectively. The results showed that, when TiBCN content was 15wt%, the microstructure of coating zone mainly composed of equiaxed grains and white lath-like crystals and that of transition zone mainly consisted of the elongated dendrite crystals and white small particles. Furthermore, the average hardness of the Ti/TiBCN cladding coating is 750HV0.2, which was about 5 times higher than that of the substrate (~127HV0.2), and the corrosion potential (Ecorr) reached −1.271V and the corrosion current density (Icorr) was 3.155e−005 A/cm2, which was one magnitude low than that of the substrate (2.269e−004 A/cm2). The narrow and shallow plowing grooves uniformly distributed on the worn surface and have less wear damage and the mass loss of the cladding coating was only 2.4mg in 20min.

Common Inspection Equipment for Coating & Paint Industry

The inspection of paint and coatings is one of the most important stages in production. Without proper inspection, it is impossible to ensure quality or determine if a coating has achieved the desired properties.

Paint and coatings industry-specific inspection equipment are designed for different applications, e.g.: durability testing, washability testing, hardness testing, glossmeter and even color measurement. Which testing equipment to choose depends on the production process, production quality requirements and the specific properties of the product being manufactured.

Washability tester: This is one of the most common paint inspection tools used in the coating industry. Washability tester measures both flash rust and salt spray resistance of a product by using a washability test bench. Flash rust is the rusting that occurs when exposed to air for 24 hours after washing with water.

Paint Microhardness Testing System: Micro hardness testing is an important tool for coating and paint testing. It utilizes a roller with the thickness of a 0.5mm steel plate in order to receive a sample from the base coat layer of the product being tested and then apply a stamping force of over 25N to measure the hardness of the material. Hardness value is normally expressed in Rockwell (HV) scale, which is determined by measuring the number of indentations made by a ruby ball under constant pressure against compound steel that has grains. The higher the hardness value, the lower the indentation.

Paint Vickers Hardness Testing System: Vickers hardness testing measures a coating or paint's ability to achieve high-gloss or passes a polish test without showing signs of flaking, cracking or disintegration. A hammer is used to repeatedly strike an aluminum plate with a specific force until it cracks. The set force required to produce a single crack is called Vickers hardness. It can be used in coating and paint inspection as well as in product quality control before packaging and shipping.

Color measurement device: Color measurement is important to determine the color of the paint or coating before applying. This will help prevent color errors, which result in poor paint quality (color reversal), reduced life, and increased cost of production.

Digital micro Vickers hardness testing system: This Digital micro Vickers hardness testing system provides a fast and efficient way to evaluate the hardness of coating layers by measuring the depth of indentation made by a ruby ball under constant pressure as it rolls against steel bars with grains. The hardness value is usually expressed in Rockwell (HV) scale, but can be converted to another standard such as Vickers (HV) scale if desired.

Rockwell hardness testing system: The Digital Rockwell hardness testing system is widely used in the industrial field to measure the surface hardness of a variety of materials such as paints, coatings, plastics, rubber and metal alloys.

Paint meter: Paint meter is a small precision device or instrument that will measure the amount or density of a particular paint or coating applied onto an object/surface. Paint meters are especially helpful when applying coatings like wall-paint, window-paint and cabinet-paint in residential homes.

Quality Inspection Equipment for Coating And Paint Industry

The majority of quality checks follow a protocol that involves multiple phases. When an evaluation goes bad, it's either the measures weren't precise or the tester didn't follow the instruction. In order to achieve the best results, you need quality inspection equipment. Here are some of the best equipment ideas you can follow for the paint and coatings industry.

Abrasion resistance testing instrument that uses brushes that slip over the surface of the material specimen, simulating everyday wear. This device is used to examine the abrasion resistance produced by a cleaner, brush, or other methods on the composite surface. The wet abrasion scrub tester can cause testable impact, and it can also simulate daily use by using various models of brushes under controlled conditions. A scrub abrasion and washability tester lets the most versatile application of the various scrub, corrosion, and washability measures. The base structure must first be chosen from two styles.

An automated coating thickness gauge may be used to measure the thickness on magnetic steel surfaces as well as non-magnetic metal surfaces like stainless steel or aluminium. For non-magnetic coatings on magnetic substances like steel, electromagnetic induction is used. For non-conductive coatings on non-ferrous metal surfaces, the eddy current concept is used. The depth of a highly acceptable is determined by measuring the film thickness. The amount of material used to achieve a certain coating thickness that provides the best security against degradation, wear, and oxidation must be determined.

A Vickers indenter and a full variety of test loads are included with the microhardness tester. On the measuring microscope, up to three of the improved long working distance targets can be placed, and an easy-to-read dual-line optical filar eyepiece is included for short and accurate indentation measurement. The hardness rating, as well as the test location results, are conveniently displayed on the touch screen LCD panel through the Digimatic micrometer heads. Data processing features such as hardness scale conversions, mathematical measurements, and OK/NG determinations are also used in the digital micro Vickers hardness testing system. Micro-hardness tester devices for Knoop and Vickers have a compact and dependable approach for precise micro-hardness testing, which can be used for quality management and metallurgical analysis.

The Rockwell scale is a hardness scale dependent on a material's indentation hardness. The Rockwell measure compares the penetration depth of a test specimen under a substantial load to the penetration depth created by a preload to measure hardness. The best GR&R performance is achieved by Rockwell hardness testers or paint meters, which attain the maximum degree of depth calculation precision and resolution possible. Digital Rockwell hardness testing system is available in a variety of sizes and capacities to fit a variety of sample sizes, as well as three distinct Rockwell standard, superficial, and twin hardness scales. The resistance of a material to norms established is known as its hardness. ASTM E-18 specifies current Rockwell Hardness test procedures, and anybody who wishes to run a Rockwell Hardness test can become acquainted with this test protocol.
