Zinc lamellar and hot zinc coatings according to the technologies of ZVK BERVEL LLC are an effective way of anticorrosion protection of high-strength fasteners
The process of preparing the surface of the substrate before applying the coating plays an important role in creating anti-corrosion protection. Properly selected surface preparation technology ensures the absence of foreign particles and moisture that prevent reliable adhesion of the entire coating as a whole. A distinctive feature of the surface preparation technology for high-strength fasteners at ZVK BERVEL LLC is the exclusion of operations that lead to surface hydrogenation. Shot blasting is used to remove corrosion products. Corrosion tests and metallographic studies were carried out to verify the effectiveness of the coatings.
