摘要
采用化学镀镍的方法对压电复合材料进行金属化。通过正交试验并结合实际生产,研究确定了压电复合材料表面化学镀镍前处理中新型粗化液、活化液以及化学镀液的最佳工艺配方和条件:粗化溶液浓度350g/L,粗化温度25℃,粗化时间25min;PdCl2浓度0.4g/L,活化温度30℃,活化时间5min;施镀温度38～43℃,施镀时间8～10min,镀液pH 8.5～9.5。利用SEM、EDS和XRD研究镀层的形貌、成分及镀层结构,采用热震实验和极化曲线测试镀层的结合力及耐蚀性。结果表明:最佳实验条件下获得的镀层均一性良好,具有较好的耐腐蚀性能及较强的结合力。
Nickel films were deposited on the piezoelectric composites by the electroless Ni plating. The optimal process and formula conditions of pretreatment process, activation process and the electroless plating solution were obtained in combination with the orthogonal test and the practical production as follows, 350 g/L of mass concentration, 25 ~C of roughening temperature, 25 min of roughening time; 0.4 g/L of PdC12, 30 ~C of activation temperature, 5 min of activation time; 38~43 ~C of plating temperature, 8~10 min of plating time and pH value of 8. 5 ~ 9. 5. The deposit＇s micro morphology and compositions of piezoelectric composites were analyzed and compared by using SEM, EDS and XRD analysis. The results show that the deposit of the optimal conditions has well uniformity, and with good adhesion and corrosion resistance.
