The compressor shell is typically stamped from hot or cold rolled mild steel or is constructed from gray cast iron. Therefore, it is often necessary to provide a corrosion-resistant coating on the compressor casing to protect it, otherwise the compressor is highly susceptible to corrosion. Particularly in the marine atmospheric environment, the compressor is more susceptible to corrosion because the marine environment is a complex corrosive environment, seawater itself is a strong corrosive medium, and at the same time, sea waves, tidal water and the like continuously impact the compressor, which directly or indirectly accelerates the corrosion process. The surface treatment is a process method for artificially forming a surface layer with mechanical, physical and chemical properties different from those of a substrate on the surface of a substrate material. The purpose of the surface treatment is to meet the requirements of corrosion resistance, wear resistance, decoration or other special functions of the product. For metal castings, mechanical polishing, chemical treatment, surface heat treatment and surface spraying are common surface treatment methods, and the surface treatment is to clean, deburr, remove oil stains, remove oxide scales and the like on the surface of a workpiece.
