摘　　要：通过对钛基体前处理、镀浴各组分的比例及镀后热处理方法的研究,提出了碱性浴钛基化学镀铂的工艺条件。克服了钛基体在氨碱性介质中易钝化的困难,实现了利用P盐为主盐、肼为还原剂的碱性化学镀铂浴,在钛基上获得了均一、牢固的铂镀层。A process was established to prepare electroless platinum coating on a titanium substrate from the alkaline bath of Pt(NO2)2(NH3)2,abridged as Pt salt throughout.Thus the conditions for the pretreatment of the Ti substrate,the bath composition,and the heat treatment method of the coating were optimized.It was found that the present process could be used to prevent the titanium substrate from passivation in alkaline bath.And it was feasible to deposit uniform Pt coating well adhered to the Ti substrate using the Pt salt as the main salt and hydrazine as the reducing agent in the alkaline bath.
