Test Background
Ceramic materials, as an important inorganic non-metallic material, have made great progress. In particular, structural ceramics are widely used in metallurgy, chemical industry, aerospace and other fields due to their high mechanical strength, high hardness, corrosion resistance, high wear resistance and other advantages.
Hardness is an important technical parameter of structural ceramics. It is closely related to the material's strength, wear resistance, toughness, material composition, microstructure, etc. The room temperature hardness test of fine ceramics can determine the Vickers hardness and Knoop hardness of fine ceramics at room temperature.
Zhongke Testing and Reliability Experiment Center has the capabilities of environmental testing and reliability performance testing of various fine ceramics, and provides professional room temperature hardness testing services for fine ceramics.
Scope of tests
Fine ceramics can be divided into two categories: structural ceramics and functional ceramics.
Structural ceramics: high-temperature ceramics, high-strength ceramics, superhard ceramics, corrosion-resistant ceramics
Functional ceramics: electronic ceramics, superconducting ceramics, optical ceramics, bioceramics, magnetic ceramics, energy storage ceramics
Test method
1. Determine Vickers hardness
Press the Vickers indenter into the surface of the sample with the test force. After maintaining it for the specified time, remove the test force and measure the diagonal length of the indentation on the surface of the sample.
2. Determine Knoop hardness
Press the Knoop indenter into the surface of the sample with the test force. After maintaining it for the specified time, remove the test force and measure the diagonal length of the indentation on the surface of the sample.
