It can resist chemical damage and has a certain mechanical strength to prevent metal materials from corroding in a humid environment. Metal anti-corrosion coating usually uses a thermal spray device when spraying. Metal thermal spraying refers to heating and melting the coating material, atomizing it into extremely fine particles with a high-speed airflow, and spraying it onto the workpiece surface at a very high speed to form a coating. According to the needs, different coating materials can be selected to obtain one or more properties such as wear resistance, corrosion resistance, oxidation resistance, and heat resistance.
