Abstract

Tribological properties of Ni₃Al-Cr₇C₃ composite coatings on carbon steel lubricated with liquid paraffin were measured by using a ball-on-disc reciprocating tribotester. Effects of load, sliding speed, sliding time to the coatings' tribological properties were investigated. The worn surface of Ni₃Al-Cr₇C₃ coatings was examined using scanning electron microscopy (SEM), electron probe microscopy analysis (EPMA) and X-ray photoelectron spectroscopy (XPS). It shows that the wear rate of Ni₃Al-Cr₇C₃ coatings is lower than the bearing steel and the Ni₃Al coating at the same test conditions. Wear rate and friction coefficient of Ni₃Al-Cr₇C₃ coatings varies with the load, sliding speed, sliding time and Cr₇C₃ phase content. The results of the experiments were well explained by analyzing wear and friction mechanism of Ni₃Al-Cr₇C₃ coatings under different tribological parameters. (C) 2000 Elsevier Science S.A.
