阅读说明：本技术 改性磷化剂、金属件及其表面磷化处理方法 (Modified phosphating agent, metal piece and surface phosphating method thereof ) 是由 王饶玲 于 2017-05-27 设计创作，主要内容包括：一种改性磷化剂,以1000重量份计,包括如下重量份数的成分：5-30份磷酸,3-10份的氧化锌,0.5-3份的钼盐,0.5-5份的硝酸钡和余量的水。改性磷化剂使用寿命长,使用温度为10-50℃,用于金属件表面预处理形成彩色的磷化层,且结构细致,附着力牢固。还公开了一种金属件表面磷化处理方法,以及通过表面磷化处理方法得到的金属件。(The modified phosphating agent comprises the following components in parts by weight in 1000 parts by weight: 5-30 parts of phosphoric acid, 3-10 parts of zinc oxide, 0.5-3 parts of molybdenum salt, 0.5-5 parts of barium nitrate and the balance of water. The modified phosphating agent has long service life and the use temperature of 10-50 ℃, is used for preprocessing the surface of a metal piece to form a colorful phosphating layer, and has a fine structure and firm adhesive force. Also discloses a surface phosphating treatment method of the metal part and the metal part obtained by the surface phosphating treatment method.)
