Abstract

Abstract

FeCrAlY,NiCrAlY₂O₃,NiCrAlY coatings on 1Cr17Ni4 stainless steel were prepared by plasma spray. Friction and wear characteristics of these coatings were studied under dry sliding of small distance. The strength of these coatings was measured by tensile method. The friction coefficients of these coatings are almost the same, and much smaller than that of 1Cr17Ni4 matrix. The wear resistance of Ni-based coatings had been improved, and wear resistance of NiCrAlY coating is the best. Wear resistance of FeCrAlY coating is worse than that of 1Cr17Ni4 matrix. The predominant wear mechanism of the coatings appeared to the plastic deformation of abrasive wear and the fatigue delamination.
