Wear Morphology and Mechanism Analysis of Plasma Spraying Nanometer Al2O3-13%wtTiO2 Coating Material

Nanometer Al2O3-13%wtTiO2 wear-resistant coating was prepared by The plasma spraying process , and the coating was tested through a SRV friction and wear testing machine, the worn surface and wear debris were observed by scanning electron microscopy, and the wear mechanism was analyzed. The friction coefficient of Nanometer Al2O3-13%wtTiO2 decreases with the increase of the load. The main wear mechanism is adhesive wear, accompanied by a small amount of abrasive wear.
