Abstract

The invention is suitable for the technical field of metal surface treatment methods, provides a stainless steel surface treatment method and aims at solving the technical problem of failure in showing stainless steel three-dimensional texture after stainless steel surface treatment in the prior art. The stainless steel surface treatment method comprises the following steps: pretreatment, namely cleaning the surface of a stainless steel substrate; impacting nickel, namely performing impacting electronickelling on the stainless steel substrate to obtain an impact nickel layer; acidic copper electroplating, namely performing acidic copper electroplating treatment on the impact nickel layer and forming a copper coating; pearl nickel electroplating, namely performing pearl nickel electroplating treatment on the surface of the copper coating and obtaining a pearl nickel layer with sand feeling; electrochroming, namely forming a protective chrome layer on the surface layer of the pearl nickel layer; and aftertreatment. The pearl nickel electroplating treatment is adopted to increase the sand feeling of the copper coating and then the surface with the three-dimensional texture can be obtained; and the electrochroming treatment is adopted to form the protective film on the surface of the pearl nickel layer, and therefore, the stainless steel substrate also has silver white metal texture.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment methods, in particular to a stainless steel surface treatment method. Background technique [0002] When performing metal surface treatment, the common way is to process the film layer on the near-field surface of the metal to obtain different surface effects. For example, apply heat-resistant ink or heat-resistant paint on the surface of the metal substrate to cover the barrier plating layer on the parts that do not need to be coated, and finally perform vacuum coating. Because the parts coated with heat-resistant raw materials are not coated with a film layer, a metal film layer effect with two colors on the surface is produced. In addition, for the surface treatment of stainless steel, ordinary electroplating is usually used to obtain a flat and smooth surface. However, the above-mentioned surface treatment methods all obtain smooth and flat surfaces, and it is difficult to re...
