Problems solved by technology

The bus bar is composed of a metal protective shell, conductive bars, insulating materials and related accessories. The conductive bars are usually copper bars made of high-conductivity copper materials or aluminum bars made of aluminum materials. Metals are easily Oxidation and passivation. At the same time, when the air contains high water vapor, the surface of the copper bar is prone to patina, and the patina cannot conduct electricity and may cause safety hazards.
In the prior art, the electroplating process is usually used to electroplate a layer of tin film on the surface of the copper bar to protect it from oxidation, but the electroplating process is relatively complicated and requires high requirements, and the electroplating industry is polluted and strictly controlled by the state, so the electroplating process It is not suitable for the production needs of enterprises in some areas, so the use of chemical precipitation to attach the antioxidants required on the surface has become a development direction
[0003] In the prior art, for example, the patent No. CN201510664159.8 discloses a method for preparing a high-temperature anti-oxidation layer on the surface of metal tungsten, which includes: polishing the metal tungsten substrate until the surface is smooth and flat, and degreasing and degreasing the polished surface Treatment: embed the treated metal tungsten base material into a molybdenum infiltrant, then heat-treat in an inert atmosphere, remove impurities after cooling, and obtain a semi-finished product with a tungsten-molybdenum solid solution layer on the surface of the metal tungsten; place the semi-finished product in a nitrogen atmosphere Carrying out heat treatment, removing impurities after cooling, and obtaining a prefabricated body with molybdenum nitride and tungsten nitride coating on the surface of metal tungsten; The surface of the metal tungsten base material is a finished product of W-Mo-N-Si series high-temperature anti-oxidation layer, which is heat-treated with an inert gas. This treatment method is unstable, and the product obtained is not easy to control. Unstable under the environment, easy to react with other substances and change its surface composition
