Description

technical field

[0001] The invention relates to a contact fatigue friction and wear testing machine, in particular to a contact fatigue friction and wear testing machine which simulates actual working conditions and can detect contact fatigue on-line. Background technique

[0002] The surface friction and wear state and contact fatigue life are one of the main means to evaluate the quality of the coating process and the surface performance of the coating material. At present, there is no complete contact fatigue friction and wear testing machine that can simulate the actual working conditions to detect the friction and wear state and fatigue life of coating materials.

[0003] Although the coating adhesion measuring instrument manufactured by Fangqun Company in the United States can measure the coating adhesion under standard microscopic conditions, the performance of the surface coating material obtained by local microscopic measurement is different from that of the surface...
