Abstract

The invention discloses an electrochemical treatment method capable of improving the surface characteristic of stainless steel. The electrochemical treatment method capable of improving the surface characteristic of the stainless steel comprises the following steps: (1) removing oil from the surface; (2) preparing polishing liquid; (3) performing electrolytic treatment. According to the treatment method, the surface characteristic of the stainless steel is effectively improved, the surface glossiness and the mirror surface effect are improved, corrosion resistance and rust resistance of the stainless steel are improved, the use quality of the stainless steel is enhanced, and strong market competitiveness is achieved.

Description

technical field [0001] The invention relates to a treatment method for stainless steel, in particular to an electrochemical treatment method for improving the surface properties of stainless steel. Background technique [0002] With the continuous improvement of people's quality of life, more and more stainless steel products have penetrated into people's daily life. Polishing is an important process in stainless steel processing and production. Traditional mechanical polishing tends to damage the workpiece. Local high temperature and hardening tend to occur during friction, which in turn changes the original metallographic structure of the metal surface and affects the further processing of stainless steel. Electrolytic polishing overcomes the disadvantages of mechanical polishing very well, but the existing electrolytic polishing technology has high temperature requirements, usually above 90°C, to ensure the quality of electrolytic polishing, which undoubtedly increases th...
