Countersunk Head Rivet Nut is a common part in mechanical equipment and plays a very important role. However, corrosion in use is a common damage. In order to prevent the Countersunk Head Rivet Nut from corrosion during use, many manufacturers will perform surface treatment on the product after it has been produced.
Standard parts are electroplated. This method is to put the standard parts in the metal solution, and then use electric current to cover the surface of the standard parts with a layer of metal. This layer of metal has many functions. For example, we can choose different plating metals according to different functions. If we want to prevent standard parts from rusting, we can electro-galvanize the surface of standard parts.
2. Mechanical plating
The mechanical plating of standard parts means that metal particles are cold welded to the standard parts to ensure certain functions of the surface layer of the standard parts. Mechanical electroplating is basically similar to electroplating, but we use different methods and the result is the same.
3. Heat treatment
For the heat treatment of the surface layer of standard parts, some standard parts, such as the relatively hard surface layer, can be heat treated to ensure that the product has sufficient hardness. This is the reason for heat treatment.
4. Surface passivation
For the surface passivation of standard parts, passivation has two main functions: one is to increase the hardness of standard parts; the other is to greatly reduce the oxidation of standard parts. In the process of fastener surface treatment, we can choose the appropriate method according to specific requirements. In this way, the fastener can play a better role during use. The same is true. Hex Rivet Nut can also use this method for anti-corrosion treatment and prolong the service life.
