Abstract

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.

Keywords: atmospheric plasma spraying; corrosion resistance; graded coating; laser remelting.
