Dacromet is a coating used for surface treatment of equipment. It is mainly applied on the surface of metal equipment to achieve a certain corrosion resistance to metal. In practical applications, it is mainly used for vehicles, mechanical equipment, and parts. In fact, in addition to using Dacromet In addition to Cromet, some companies often use hot-dip galvanizing process in order to reduce the corrosion performance of metal parts. The main purpose of this process is similar to that of Dacromet. Let's analyze it with the Dacromet manufacturer in Xinxiang.


1. Barrier effect: Due to the lamellar overlap of flake zinc and aluminum, it hinders the process of water, oxygen and other corrosive media from reaching the substrate, and can play an isolation shielding role.

2. Passivation: During the treatment of dacromet, chromic acid reacts with zinc, aluminum powder and base metal to form a dense passivation film, which has good corrosion resistance.

3. Cathodic protection: The main protective function of the zinc-aluminum-chromium coating is the same as that of the galvanized layer, which is to provide cathodic protection for the substrate.

Hot dip galvanized:

The formation process of the hot-dip galvanized layer is the process of forming an iron-zinc alloy between the iron substrate and the outer pure zinc layer. The iron-zinc alloy layer is formed on the surface of the workpiece during hot-dip galvanizing, which makes the iron and pure zinc layer very good. In combination, the process can be simply described as: when the iron workpiece is immersed in the molten zinc liquid, a zinc and body-centered solid solution is formed on the interface.

The above are some basic knowledge of Dacromet and hot-dip galvanizing shared by Xinxiang Dacromet manufacturers, which also increases our understanding of Dacromet and hot-dip galvanizing.
