dc.description.abstractNi-W-B/ZrO2 composite coating was electrodeposited from the Ni-W-B electrolyte solution containing zirconia particles. The electrodeposition, heat treatment, structure, surface morphology, microhardness, and corrosion resistance of the composite coating were studied by means of differential scanning calorimeter (DSC), X-ray diffraction (XRD), scanning electron microscopy (SEM), and electrochemical techniques. The results showed that the mass composition of the obtained Ni-W-B/ZrO2 composite coating was Ni 47.5%, W 40.9%, B 0.9% and ZrO2 10.7%. DSC combined with XRD results illustrated that zirconia took a remarkable influence on the structure of Ni-W-B matrix, leading the composite coating to a more obvious amorphous characteristics. The composite coating presented in higher microhardness compared to Ni-W-B alloy, granular structure with grain boundaries and. crack-free. Zirconia particles were dispersed in the Ni-W-B matrix. After heat treatment at 400 degreesC for 1 h, surface morphology of the coating was kept almost no changes. The structure of the matrix was transferred to a crystal of Ni-W solid solution, and W was segregated to the surface of the deposit. The microhardness and corrosion resistance were enhanced, whereas most of zirconia particles were gotten rid of from the surface layer.zh_CN
