摘要：The NiCr-Cr3C2 coatings were deposited on 38CrMoAl substrate by a laser hybrid plasma spraying (LHPS) technology in this study. The coatings' microstructures and anti-wear performances with different laser power were characterized using an optical microscope, a scanning electron microscope, and the SRV test. The test results indicated that the laser power has great effect on the microstructure and performances of the LHPS coatings. And when the laser power is at the appropriate value, it can make the coating have more compact and homogeneous microstructure, exhibit less pores or micro-cracks, and the higher bonding strength and more excellent anti-wear performance of the coating are achieved. © (2014) Trans Tech Publications, Switzerland.
