| titleOfInvention | A kind of metal surface treatment process |
| abstract | The invention discloses a kind of metal surface treatment process, which is characterized in that includes the following steps：Surface cleaning processing, micro- humidification process, surface scale processing, surface wax, oil processing, secondary cleaning, activation processing, nickel plating, copper plating treatment, oil spout.Wherein, surface scale processing is to put metal to be processed in the solution being made of sodium dichromate, ammonium sulfate, ammonium hydroxide, water into, impregnates 10-20min under the conditions of 30-40 degree temperature；Oil spout is that the metal after nickel plating, copper plating treatment is carried out injector surface processing under vacuum conditions.A kind of metal surface treatment process of the invention, obtained metal skin hardness height, corrosion resistance and crocking resistance is good, and high-temperature behavior is high；Metal surface treatment process simultaneously in the present invention is simple, and by stringent process parameter control, the speed that can descale is fast, can be reduced part base solid damage, removes more thorough. |
