摘要
The effect of ceria (CeO2,) on the wear and corrosion of laser-clad nickel-based alloy coatings was investigated. The results of microstructure observations, wear tests and corrosion tests show that the addition of CeO2, can modify the microstructure and properties of laser-clad coatings. The microstructure gets refined, the microhardness is increased, the inclusion percentage is reduced and the wear resistance and corrosion resistance are both improved. The mechanism of these effects is also discussed in this paper. (C) 1997 Elsevier Science S.A.
