Abstract

The invention relates to an electroplating titanium cadmium auxiliary anode and an application method thereof, and a technology method for improving the quality of an electroplating cadmium titanium coating of a complex shaped part. The auxiliary anode is sleeved with a layer of plastic braid web tube, and a layer of cloth sleeve is arranged between the web tube and the anode in a sleeving mode, so that the quality of the electroplating cadmium titanium coating of the complex part is improved, defects of pitting, pinholes and coating-free parts on the surface of the coating are overcome, and meanwhile, the adhesion and corrosion resistance of the coating are improved. The electroplating titanium cadmium auxiliary anode and the application method thereof can overcome various electroplating defects caused by the low purity of the cadmium auxiliary anode, and are simple and efficient.

Description

technical field [0001] The invention relates to an auxiliary anode for electroplating titanium and cadmium and a method for using the same, and a process method for improving the quality of electroplating titanium and cadmium coatings for parts with complex shapes. Background technique [0002] The electroplating titanium cadmium process is a low hydrogen embrittlement and high corrosion resistance protection process independently developed by my country in the 1980s. It is mainly used in the surface protection of high-strength and ultra-high-strength steel. At present, it has a high degree of surface treatment in my country's aviation industry. Applications. [0003] For the titanium-cadmium process, if the surface of complex parts is blocked due to the electroplating power line during the electroplating process, defects such as "pitting, pinholes, and partial no coating" will often appear on the appearance of the coating, especially in the plating solution with a high conce...
