Research on the wear performance of reactive plasma deposited TiB2-TiC0.3N0.7 matrix coating

Abstract

Wear performance and behavior of as-sprayed TiB2-TiC0.3N0.7 matrix coating were investigated with different rotation speeds of counterpart and applied load. Analytical balance was used to weigh wear quantity. Scanning electron microscopy was used to observe surface morphology, abrasion scratch, and wear debris was researched through an energy dispersive spectrum. It is found the mass loss of matrix coating increases with the loading load increment at a low rotation speed of the counterpart. And wear loss decreases first and then increases with the increment of loading load at the high rotary speed of the counterpart. The wear mechanism of abrasive wear, adhesion wear, oxidation wear, and fatigue wear appear during the test of composite coatings at different rotation speeds of the counterpart and applied load.
