Galvanized Layer Formation Process

Traffic Hot-dip Galvanized Guardrail formation process of the hot-dip galvanized layer is the process of forming an iron-zinc alloy between the iron matrix and the outermost pure zinc layer. The iron-zinc alloy layer is formed on the surface of the workpiece during hot-dip plating, so that the iron and the pure zinc layer are well combined. Traffic Hot-dip Galvanized Guardrail The process can be simply described as: when the iron workpiece is immersed in the molten zinc solution, a solid solution of zinc and α-iron (body center) is first formed on the interface. Traffic Hot-dip Galvanized Guardrail is a crystal formed by dissolving zinc atoms in the base metal iron in a solid state. The two metal atoms are fused, and the attraction between the atoms is relatively small. Therefore, when zinc reaches saturation in the solid solution, the atoms of zinc and iron diffuse into each other, and the zinc atoms that diffuse into (or infiltrate into) the iron matrix migrate in the matrix lattice and gradually form an alloy with iron, while the iron that diffuses into the molten zinc liquid forms an intermetallic compound with zinc, and sinks into the bottom of the hot-dip galvanizing pot, which is zinc slag. When the workpiece is removed from the zinc dipping solution, a pure zinc layer is formed on the surface, which is a hexagonal crystal. Its iron content is not more than 0.003%.
