Abstract:In order to investigate the relationship between Ce(SO4)2 concentration and surface performance, a series of workpieces coated with Ni-W-Ce alloy was fabricated by Jet-Electrodeposition. The cellular structure was observed by SEM, and the composition of coating elements was analyzed by EDS. XRD analysis showed that the coating had lattice distortion. LEXT4100 laser confocal microscope observed wear mark and found that the friction mechanism was to be changed. The results indicate that the addition of Ce(SO4)2 improved the surface micromorphology of the coating, and the best surface quality occurred when the concentration is 0.5g/L. Meanwhile micro-hardness, wear resistance and corrosion resistance show a rule of first getting better and then getting worse with the concentration increasing. When the concentration of Ce(SO4)2 is 0.5g/L, the micro-hardness reached the peak value of 519.69HV0.1.The wear resistance was the best as the wear resistance mark parameters dropped to the valley value. The corrosion resistance was also the best, which the corrosion potential was -0.5537V and the arc reactance radius of the minimum.
