Structure and properties of Ni-based deposited layer produced by a laser-powder surfacing were examined. It was established that it possible to produce coatings with a microcrystalline, amorphous-crystalline or amorphous structure depending on the surfacing technological conditions. Test on corrosion resistance and wear were performed. It was found that it is rational to use the deposited layers with amorphous-crystalline structure for the parts operating in aggressive media and in the conditions of abrasive wear.
Keywords: laser surfacing, nickel-based alloys, structure, corrosion resistance, wear resistance
