压电陶瓷表面酸性化学镀镍磷

以次亚磷酸钠为还原剂,在压电陶瓷表面进行酸性化学镀镍磷。采用正交设计法,通过测试镀液中各组分对镀层结合强度和沉积速度的影响,选出最佳的酸性化学镀配方。研究了粗化时间对镀层结合强度的影响,同时检测了镀层的耐蚀性。实验结果表明:压电陶瓷表面化学镀的镀层具有优良的结合力和耐海水腐蚀性能。

Acid electroless nickel-phosphorus plating on PZT ceramic

Acid elect roless nickel-phosphorus plating on PZT ceramic was studied with hypophosphite as a reducing agent . The plating bath was optimized by investigating the effect of the compositions in the plating bath on adhesive strength and deposition rate with the perpendicular design method. At the same time , the effect of roughening time on the coatingps adhesive st rength and the corrosive resistance of the film were examined. Experimental results indicated that the film on PZT had a excellent adhesive st rength and a seawater corrosion resistant property.
