摘要
针对烧结多孔钛板镀铂工艺的提高,为解决前处理过程中表面除油不彻底、酸洗刻蚀不理想的问题,采用无水乙醇除油与50 wt.%的硫酸作为酸洗刻蚀剂前处理的方法。研究了烧结多孔钛板镀铂工艺中不同的除油剂与刻蚀剂对铂镀层自身致密度及与钛基材结合度的影响。结果表明:在使用无水乙醇除油剂和沸腾状态下50 wt.%硫酸刻蚀相结合的条件下,铂镀层紧致且与钛基材结合度较高。采用无水乙醇除油与硫酸刻蚀的方法可以提高镀层的致密度与结合度。
In order to improve the platinization process of sintered porous titanium plate and solve the problems of incomplete surface oil removal and unsatisfactory pickling etching during the pretreatment process,anhydrous ethanol oil removal and 50 wt.%sulfuric acid were used as the front of pickling etching agent.The effects of different oil remover and etcher on the self-density of platinum coating and the binding degree of titanium substrate in sintered porous titanium plate platinization were studied.The results show that the platinum coating is compact and has a high binding degree with titanium substrate under the conditions of anhydrous ethanol degreasing agent combined with 50 wt.%sulfuric acid etching at boiling state.The density and bonding degree of the coating can be improved by the method of oil removal by anhydrous ethanol and etching by sulfuric acid.
