Abstract

The invention discloses a method for establishing a diamond-like film on the surface of metal by electrolyzing organic matter. According to the method, a stainless steel electrode with a thin manganese oxide layer being deposited on the surface serves as the anode, a polished metal sheet serves as the cathode, constant-voltage electrolysis is conducted in an electrolyte solution containing carbon source organic matter, and the diamond-like film is obtained on the cathode. According to the preparation method, the process is simple, operation is easy, no complex equipment is needed, the cost is low, the diamond-like carbon film can grow on the surface of a substrate with the complex morphological structure, and the film base binding force is good.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a method for preparing a diamond-like film, in particular to a method for constructing a diamond-like film on a metal surface by electrolyzing organic matter. Background technique [0002] Compared with other metal corrosion-resistant materials such as stainless steel, copper has the advantages of good electrical conductivity, thermal conductivity, wear resistance and corrosion resistance, and easy processing. It is widely used in various fields from daily chemical industry to marine exploration. However, various copper alloys currently on the market are often difficult to meet the requirements of practical applications in terms of seawater corrosion resistance. In recent years, with the improvement of comprehensive national strength, my country is increasing the development and utilization of the ocean, and it is of great significance to actively develop new corrosion-resistant cop...
