Abstract: The NiCrAlY coatings were deposited on 38CrMoAl substrate by a laser hybrid plasma spraying (LHPS) technology in this study. The coatings' microstructures and anti-corrosion performances with different laser power were characterized using an optical microscope, a scanning electron microscope, and the Neutral Salt Spray(NSS) test. The test results indicate that the laser power has great effect on the microstructure and performances of the LT-I PS coatings. And when the laser power is appropriate, it can make the coating has more compact and homogeneous microstructure, exhibit less porosities or micro-cracks, higher bonding strength and more excellent anti-corrosion performance.
