Application scope:
In terms of material research and scientific experiments, the low load Vickers hardness test is used to test the hardness of small precision parts, heat treatment, carbonization, quenching and hardening layers, surface coatings, hardness of steel, non-ferrous metals, thin sheet materials and fine wire materials, hardness near the cutting edge, hardness of dental materials, etc. It can also test the hardness and depth of the surface hardening layer. It can also be used to test non-metallic materials such as glass, jewelry, and ceramics that cannot be tested using the Rockwell test method and other relatively high test forces. It can follow the structure of metals and test the internal hardness of materials such as induction hardening or carburization.
Vickers test principle:
The Vickers hardness test is conducted by using a 136 ° diamond indenter to press a specified test force (F) into the surface of the tested object. After maintaining the test force for a specified period of time, the test force is removed, and the diagonal (d) of the indentation on the surface of the specimen is measured using a micrometer eyepiece. The average pressure (N/mm2) borne by the conical surface area of the indentation is calculated, which is the Vickers hardness value. (See Figure 1.1 for details).
