- Abstract:
- On the MM -200 -ring contact wear testing machine, the plasma sprayed chromium -chromium -nickel chromium coating on the sintering Al2O3, the hot pressure sintering SI3N4, the SIC and the plasma spray TIO2 coating in the four ceramic materials and the amount of rubbing coefficient and rubbing in dry friction; Technologies such as EDAX and XRD observe and analyze the appearance, material metastasis, and physical transformation of frictional side materials; discuss the microscopic structure and certain physical properties of friction side materials and some physical properties, mechanical performance on the effects of friction and wear of chromium carbide -nickel chromium coating. As a result, the grinding amount of coatings is not only very different from its wear. Large, and its friction and wear mechanism is different. The transfer of abrasive materials to the coating surface during friction and wear is conducive to improving the wear resistance of coating. The smaller the size and elastic modulus of the pairing ceramics, the higher the thermal conductivity coefficient, the better the pairing performance of the chromium -nickel chromium coating.
