Nd-Fe-B As technology is developing new energy. In environmental protection, new energy, industrial, automotive, computer and a number of sophisticated development of industries occupying a pivotal position. NdFeB magnets have reached a certain plating applications also need some protection. To ensure that the oxidation of NdFeB will not be soon.
Nd-Fe-B magnets plating pre-treatment is divided into: oil removal and in addition to oxides of two categories. Treatment methods include mechanical methods and chemical and electrochemical methods two categories, mechanical processing includes: polished, barrel polishing, polishing, brushing, etc.; chemical and electrochemical methods include: chemical degreasing, electrochemical degreasing, ultrasonic degreasing and chemical polishing. If you want to electroplating non-metallic materials, but also the need for plating pre-treatment, but the process than the pre-treatment of metal materials to be more complex, in addition to the surface degreasing, focusing on the surface of metal processing.
