摘要

In the present study,20 wt.% ZrO2-Al2O3-17 wt.%TiO2 powders were sprayed using a plasma-spray technique after a NiAl bond layer was deposited on plain carbon steel substrate.The produced coatings were characterized by X-ray diffraction(XRD),scanning electron microscope(SEM)including energy-dispersive spectroscopy(EDS).The tribological properties of coatings against hard alloy ball were investigated by using a pin-on-disc tribo-meter under dry environments.The predominant wear mechanism of coating is fatigue.
