Abstract

The electrodeposited ZrO₂-Ni functionally graded coating was fabricated by controlling the ZrO₂ concentration in the bath, and the microstructure was analyzed by X-Ray Diffraction (XRD) and Electron Probe Microanalysis (EPMA). The results show that the functionally graded coating has excellent compositional gradient distribution from the substrate to the surface. The content of ZrO₂ is up to 14.4 vol% in the surface layer and the coating consists of the t-ZrO₂, m-ZrO₂ and Ni phases. Owing to the ZrO₂ particles pressed by Ni atoms during electrodepositing, t→m transformation has occurred.
