1、磷化过程的主要反应机理如何?答:磷化处理工艺发展至今已比较成熟,但人们对磷化处理原理的认识还不十分清楚,存在着一些争论。目前普遍认同的机理是由如下步聚组成:①酸的浸蚀使基体金属表面H+浓度降低Fe+2e→Fe2+2H--+2e→2[H](1)→H2②促进剂(氧化剂)加速[O]+[H]→[R]+H2OFe2++[O]→Fe3++[R](2) 1, the main reaction mechanism of the phosphating process how? A: Phosphating process has been more mature, but people are not very clear understanding of the principle of phosphating, there are some controversies. The current generally accepted mechanism is composed of the following steps: ① Acid etching reduces the concentration of H + on the metal surface of the substrate Fe + 2e → Fe2 + 2H - + 2e → 2 [H] (1) → H2② (oxidant) Accelerate [O] + [H] → [R] + H2OFe2 ++ [O] → Fe3 ++ [R] (2)
