Four surface treatment methods for fastener anti-corrosion

Fasteners are the most common parts in mechanical equipment, and they are also very important to function. Machines that operate like air compressors are particularly large, and the role of fasteners can be imagined. However, corrosion is the most common problem during the use of fasteners. In order to prevent the corrosion of fasteners during use, the manufacturer will surface the fasteners after the fasteners are produced. So, which surface treatments can improve the corrosion resistance of fasteners? In industrial manufacturing, there are mainly four surface treatment methods to prevent corrosion of fasteners. When purchasing air compressors, we can combine the actual working conditions and pay attention to the anti-rust treatment method of fasteners.

1 Plating Electroplating the standard parts by placing the standard parts in a metal solution and then applying a current to the surface of the standard part with a layer of metal. There are many effects on this layer of metal. For example, we can use some different functions. Choose some different plating metals, if we want to prevent the standard parts from rusting, then we can plate zinc on the surface of the standard parts. 2 Mechanical plating The mechanical plating of standard parts is to let the metal particles cold-weld the standard parts to ensure some functions of the surface of the standard parts. Mechanical plating and electroplating are basically similar, except that the method we use is different, and the result can be said to be the same. 3 Heat treatment The surface of the standard part is heat treated. There are some standard parts, such as the hard-drilled surface of the self-drilling screw, so you can heat-treat the self-drilling screws to ensure that the self-drilling screws have sufficient hardness. This is the reason for the heat treatment. 4 Surface passivation For standard surface passivation, passivation has two main functions, one is to enhance the hardness of the standard part, and the other is to greatly reduce the oxidation of the standard part. When performing fastener surface treatment processes, we can choose the most appropriate method based on the specific needs. This way the fasteners can play a better role during use.
