The Vickers hardness tester is used to measure the macro and microhardness of materials. It was developed as an alternative to the Brinell Method, and is easier to use when compared to other hardness measurement tests. One of its main advantages is that its calculations are independent of the size of the indenter. Its wide measuring scale makes it ideal for measuring materials independent of their hardness levels.
Uses of the Vickers hardness test
The Vickers hardness tester measures the hardness of a material based on its ability to withstand plastic deformation from a standardized source. Some of the materials that can be measured using this hardness test include composites, metals, and ceramics, among other materials of different hardness levels. The units of measurements given by this test are either in the Diamond Pyramid Hardness (DPH), or the Vickers Pyramid Number (HV), which can then be converted to Pascal units. When performing a hardness test, it is important to take into consideration the required distance between indentations and that between the indentations and the edge of the material being tested to ensure accurate results.
Uses in the industry
Some of the major uses of this test are to evaluate materials on how they will perform under certain conditions. This is to aid in quality control when manufacturing materials and also for developmental purposes. The hardness of a material indicates its ductility and wear resistance. Some of the areas where this test is routinely used are in the automotive industry, aerospace, and in laboratories for common and advanced tests.
