化学镀Ni-P合金镀层用光亮剂研究

Study on brightener for electroless Ni-P plating

考察了电镀镍用中间体DEP、PME、BSI、VS、PS、PPS-OH等在化学镀镍中的使用可行性,用正交试验法对其用量进行了优化,并研究了各种中间体用量对化学镀镍层光泽度的影响趋势,最后用quanta 200型扫描电镜对使化学镀Ni-P合金镀层使用光亮剂前后的表面形貌进行了对比观察与分析,结果表明:电镀所用之光亮剂中间体对提高化学镀层的光泽度同样有效,并且当光亮剂组分含量为DEP 45 mg/L、PME 15 mg/L、BSI 750 mg/L、VS 30 mg/L、PS 200 mg/L、PPS-OH 400 mg/L、OP-10 10 mg/L时镀层光亮性最优.

The feasibility of intermediate DEP,PME.BSI.VS,PS.PPS-OH applied at Electroless Ni-P Plating, which have applied at electro nickelling,were investigated.Content of the brightener component were optimized by orthogonal test,and their effect on glossiness of electroless Ni-P coating were studied.The surface toppgraphy of the Electroless Ni-P coatings both before and after the brightener used were observed.The result shows that the optimal brightness of the electroless Ni-P plating was obtained when content of DEP,PME,BSI,VS,PS,PPS-OH and OP-10 is 45 rag/L,15 rag/L,750 mg/L,30 mg/L,200 rag/L,400 mg/L and 10 mg/L,respeetively.
