Abstract

The invention discloses a shell metal stamping part surface treatment technique which comprises the following steps: 1) mixing 65 parts by mass of ethanedioic acid, 7 parts by mass of zinc nitrate, 5 parts by mass of sodium molybdate, 2.3 parts by mass of nickel nitrate, 2 parts by mass of coconut diethanol amide, 3 parts by mass of phytic acid and 2 parts by mass of dodecyl trimethyl ammonium sulfate, and reacting at 115 DEG C for 3 hours to obtain a metal surface treating agent; 2) mixing 17 parts by mass of metal surface treating agent and 136 parts by mass of water to obtain a surface treatment working fluid; and 3) heating the surface treatment working fluid to 54 DEG C, and putting the metal stamping part in the surface treatment working fluid to perform surface treatment for 27 minutes. The surface treatment technique can enhance the oxidation resistance and corrosion resistance of the metal stamping part.

Description

technical field [0001] The invention relates to a surface treatment process of metal stamping parts of casings. Background technique [0002] The anti-oxidation and anti-corrosion capabilities of existing metal stamping parts need to be improved. Contents of the invention [0003] The purpose of the present invention is to provide a surface treatment process for the metal stamping parts of the casing, which can improve the oxidation resistance and corrosion resistance of the metal stamping parts. [0004] In order to achieve the above object, the technical solution of the present invention is to design a surface treatment process for metal stamping parts of the casing, including the following steps: [0005] 1) Take 65 parts by mass of oxalic acid, 7 parts by mass of zinc nitrate, 5 parts by mass of sodium molybdate, 2.3 parts by mass of nickel nitrate, 2 parts by mass of coconut oil fatty acid diethanolamide, 3 parts by mass of phytic acid, 2 parts by mass of twelve Alk...
