In the hardware industry, what 'stirring' word describes the process of coating of iron/steel with zinc to prevent rusting?
Zinc flake coating typical galvanic zinc coating, which in the tests (generally run in accordance with ISO 9227) often achieve only 96 to 200 hours. The material for the zinc flake coatings gets supplied in liquid form and needs to be prepared to the desired conditions before application. The viscosity, temperature and stirring time prior to application all play an important role here. The material can be applied using the following application techniques: Prior to coating, the parts’ surface needs to be pre-treated. Pickling with acids (e.g. sulfuric or hydrochloric acid) produces atomic hydrogen and can penetrate into the steel structure and make
Zinc flake coating of the automotive industry have set new objectives. Corrosion protection and appearance are no longer the only and most important characteristics. In addition to the applications in the automotive industry, these coating systems are also found in wind power systems, the construction industry, electrical equipment (plant construction), trucks and other markets as well. Zinc flake coatings create what is known as cathodic protection: the less noble zinc ‘sacrifices’ itself in order to protect the underlying metal. Steel can be protected in this way. The coating thickness is often between 5 µm and 15 µm, with thicker layers also possible where
