Hot Galvanizing Spring Washer, Spring Washer, Hot Galvanizing, Direct From The Manufacturer
Product Description
Compared with the galvanizing pad, the zinc layer on the surface of the galvanizing pad is thick, with strong adhesion, and the zinc layer is not easy to fall off. Generally, the thickness of the galvanizing layer is 5-15 μ m, while the hot galvanizing layer is generally more than 35 μ m, even up to 200 μ M. The coating is compact and free of organic inclusions. As we all know, the mechanism of zinc's resistance to atmospheric corrosion includes mechanical protection and electrochemical protection.
Under atmospheric corrosion conditions, there are ZnO, Zn (OH) 2 and basic zinc carbonate protective films on the surface of zinc layer, which can slow down the corrosion of zinc to a certain extent. This protective film (also known as white rust) will be damaged and form a new film. When the zinc layer is seriously damaged and endangers the iron matrix, the zinc produces electrochemical protection on the matrix. The standard potential of zinc is - 0.76v, the standard potential of iron is - 0.44v.
When the zinc and iron form a micro battery, the zinc is dissolved as an anode and the iron as a cathode is protected.
Obviously, the resistance of hot-dip galvanizing to atmospheric corrosion is better than that of electro galvanizing.
