Zinc plating is low cost and easy to process. Electrogalvanized layers are anodized for steel fasteners and can provide electrochemical protection. The thickness of electrogalvanized layer is generally 5-12μm. After chromate passivation treatment, its anti-corrosion performance is greatly improved and it can resist the neutral salt spray test of 48-96h. Therefore, galvanization is in the threaded fastener. Has been widely used.
The problem of non-uniformity in the thickness of the galvanized layer is a non-negligible problem in the manufacture of threaded fasteners, which is related to the screw threading and plating quality.
The thickness of the electrogalvanized layer has a great influence on the quality of the zinc coating. The main features are as follows: (1) The corrosion resistance of the zinc coating depends on the thickness of the coating and the exposure environment. The harsher the conditions of use, the thicker the coating, and the resistance of the entire coating. Corrosion performance in turn depends on the corrosion resistance of the weakest portion of the coating including where the local thickness is the smallest. (2) Roughness, nodules, shedding, and other rickets are likely to occur where the zinc layer is too thick. (3) Where the zinc layer is too thin, the glossiness is poor, and it is dark and hazy. It is easy to expose the bottom in the process of light emission and passivation
