Abstract

The electrodeposited ZrO 2 Ni functionally graded coating was fabricated by controlling the ZrO 2 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 ZrO 2 is up to 14.4 vol% in the surface layer and the coating consists of the t ZrO 2, m ZrO 2 and Ni phases. Owing to the ZrO 2 particles pressed by Ni atoms during electrodepositing, t→m transformation has occurred.
