You may not be unfamiliar with the Dacromet anti-corrosion process. Below we invite Shanghai Dacromet manufacturers to introduce some advantages of the product:
One of the characteristics of Dacromet treatment is that the workpiece is not pickled during the pretreatment. Hydrogen embrittlement is a drawback that cannot be completely overcome by the traditional electro-galvanizing process. Since the Dacromet process does not pickle the workpiece, it can avoid hydrogen ions from corroding the steel substrate. , so Dacromet coating is especially suitable for surface corrosion protection of 6-1000N\/mm2 high-strength bolts and springs.
After the Dacromet coating is baked at high temperature, a coating composed of zinc, aluminum flakes and compound salts is formed on the surface of the workpiece. It has a good bonding force with the steel substrate, so its adhesion is quite good. At the same time, the coating surface formed in this way is conducive to the recoating of various coatings. Dacromet surface treatment technology is developing rapidly at present, with continuous innovation, and its advantages in the future will be more obvious.
