In this study, Ni-Cu-W graded coatings are produced by atmospheric plasma spraying and subsequently remelted by laser. The surface morphology, hardness, compositional fluctuations and corrosion resistance of the Ni-Cu-W coating are investigated. The coatings after laser remelting are densified and become more homogenous with an excellent corrosion resistance and high hardness, which can be used to explore the new materials.

在本研究中，通过大气等离子喷涂制备了Ni-Cu-W梯度涂层，随后用激光进行重熔。研究了Ni-Cu-W涂层的表面形貌、硬度、成分波动和耐腐蚀性。激光重熔后的涂层致密化，变得更加均匀，具有优异的耐腐蚀性和高硬度，可用于探索新型材料。
