Nail-making mechanical galvanizing is a kind of anti-corrosion coating that is different from electro-galvanized, hot-dip galvanized iron, and Dacromet. Its process characteristics are: room temperature production operation, coating formation does not belong to electrodeposition, it is loaded by parts plating barrel The rotation of the tube makes the parts and media in the cylinder collide with each other, and realizes the transfer of the nail-making machinery industry to form a coating; the coating structure is a fine-grained spherical zinc powder that is deformed by the collision and deformation of the nail-making mechanical force to become a flat, dish-shaped zinc particle layer. It is superimposed to condense into a coating. This structured coating has the basic physical characteristics of metallic zinc. The function of the coating is to provide the basic iron parts with an anodic protective coating required for anti-corrosion. The process characteristics are: it does not produce hydrogen embrittlement hazards for high-strength steel industrial parts and the heavy-duty anti-corrosion coating of small barrel-platable parts replaces the hot-dip galvanizing process, which has a competitive advantage in industrial applications.
