- 针对TC18钛合金筒形、多孔零件内外表面分两次镀铬存在过腐蚀的问题，设计了对内外表面一次电镀成品铬的工艺，通过协调镀前尺寸、使用合适规格内阳极、专用工装及优化的电镀参数，保证了内外表面同时电镀成品铬的需求。结果表明：协调的镀前尺寸及确定的内阳极规格合适，设计的工装、采用的保护方法及电镀工艺可靠、稳定，零件铬层厚度及镀后尺寸满足图样要求。
- Abstract:
- In order to solve the problem that the inner and outer surfaces of TC18 titanium alloy cylindrical and porous parts are over corroded by electroplating twice, the finished product of primary chromium plating on the inner and outer surfaces is designed. The process ensures the simultaneous plating demand of finished chromium on the inner and outer surfaces by coordinating the pre-plating size, using the appropriate specification of the inner anode, the special tooling and the optimized plating parameters. The results show that the coordinated pre-plating size and the determined inner anode specification are suitable, and the designed tooling, the protection method and the electroplating process are stable. The thickness of chromium layer and the size after plating meet the requirements of the pattern.
