Hardness test (hardness test) is the performance measurement of metal material degree of hardness, hardness test indentation is the surface of the sample, keep a period of time, unloading test force, test indentation size, the calculation of the value of hardness.
Mechanical properties of a material for measuring the surface hardness of solid materials. Hardness test is one of the most simple material test, compared with other materials, such as tensile test, impact test and torsion test, it has the following characteristics:
1, the test can be directly carried out regardless of parts size, thickness and shape on the part;
2, the test left on the surface is very small, parts are not damaged;
3. The test method is simple and rapid. Hardness testing is widely used in the mechanical industry to test the quality of raw materials and parts after heat treatment. Because the hardness and other mechanical properties have a certain relationship, but also can be estimated according to the hardness of the parts and other mechanical properties of materials. Hardness test method is very much, generally divided into scratch method, indentation method and dynamic method 3 kinds.
Hardness test methods are: scratch method, indentation method, dynamic method, wear method, cutting method.
