Dacromet is also known as zinc-chromium film coating, which has high corrosion resistance and is currently in the embryonic stage. It is a high-tech clean production process and an epoch-making new leap in the surface treatment industry.
This process can replace electrogalvanizing, cadmium, zinc-based alloy, hot-dip galvanizing, thermal spray galvanizing and mechanical galvanizing of steel parts. Its main advantages are:
1. High corrosion resistance: Dacromet metal coated products can withstand smoke for 600-1200 hours, which is 7-10 times higher than electro-galvanized;
2. No hydrogen embrittlement: the coating process does not produce hydrogen embrittlement, especially suitable for surface anti-corrosion treatment of high-strength bolts and components;
3. High weather resistance: adapt to various climate changes and cold and heat changes, used for sun-exposed parts and water-immersed parts;
4. High heat resistance: the heat resistance temperature can reach 300 degrees Celsius, which is suitable for high-strength components of automobile and motorcycle engines;
5. Cleanliness, no need for pickling, no harmful gas and liquid discharge, it is a clean production process.
Dacromet coating and Dacromet metal coating processing products have been widely used in automobiles, motorcycles, building components, bridges, electric power, highway guardrails, railways, ships and military industries and other fields.
