Creation of Corrosion-Resistant Coatings Based on Zinc in an Electromagnetic Field on Steel Punching Rivets

The article described the process of creating the protective corrosion-resistant coating of zinc on the product «Punch rivet» by using an electromagnetic field. The currently most common methods of anti-corrosion treatment do not provide the required protection, therefore, the rarest type of protection of products against corrosion is used - thermal diffusion zinc plating. This method of applying a protective coating makes it possible to achieve its preservation when the sheet steel is punched by a rivet, which improves the quality of the connection and prolongs the life cycle of the product. As part of the study, the influence of the heating mode and the percentage ratio of the components of the zinc-containing mixture on the quality of the applied corrosion-resistant protective coating was considered. The results obtained allowed to determine the optimal mode for applying a protective zinc coating to the «Punch rivet» product, which ensures the resistance of the rivet coating to mechanical stress and the saving of the product geometry after thermal diffusion treatment.
