Electroless Nickel Plating on Zirconium Dioxide Ceramics ZHANG Gui min 1,TAN Yue hua 2,ZHANG An fu 1,LIAO Hong wei 1 (1.School of Materials Science and Engineering,WUT,Wuhan 430070,China; 2.College of Chemistry and Chemical Engineering,Urumqi 830046,China)Special technology of pretreatment for electroless nickel plating on ZrO 2 ceramic have been studied. And the influence of these factors, for example, the density of the reductants, the type and density of the complex agents, PH value, as well as the temperature on the rate of electroless plating and the mount of P countained in the Ni-P coating are investigated; The properties, the morphology and the structure of electroless nickel coating are analyzed.The results show the even and compactive Ni-P coating with good adhesion and corrosion resistance can be obstained in the special technology.ZrO 2 ceramic; electroless nickel plating; the velocity of electroless plating; properties
