Information

　　To effectively prevent the corrosion of metal parts and equipment, the current anti-rust methods can be roughly divided into four categories:

　　1. From the internal structure of the metal to change its corrosion resistance

　　This method is to change the internal structure of the metal into alloy steel, stainless steel, etc., considering the metal material itself. Generally, alloying elements such as silicon, manganese, chromium, vanadium, titanium, boron, tungsten, molybdenum or rare earth are added during steelmaking to combine iron with these elements to enhance corrosion resistance.

　　2. Metal surface conversion layer and "permanent" surface coating

　　This method can be divided into: chemical and electrochemical conversion coatings such as oxidation, phosphating, chromating, fluorination, etc., surface alloying; such as nitriding, metalizing (chromizing, aluminizing, nitriding, etc.) I Metal coating, such as electroplated metal, sprayed metal, chemical plating, vapor plating, melting plating, etc., non-metal coating. Inorganic coatings such as enamel, ceramic coatings, organic coatings such as paint, plastic, rubber, etc. coatings.

　　3. Cathodic protection

　　Even if the metal surface becomes a cathode. For example, magnesium blocks are used as anodes in seawater, and they are connected with steel plates to transform the steel plates into cathodes, thereby protecting the steel. Underground pipelines and chemical equipment can also be protected by adding an electrode with the same method.
