1. Electroplating the standard parts, this method is to put the standard parts into the metal solution, and then pass the current to cover the surface of the standard parts with a layer of metal. There are many effects on this layer of metal. For example, we can base on some different The function of choosing some different plating metals, if we want to prevent the standard parts from rusting, then we can electroplate the surface of the standard parts with zinc.
2. Heat treatment on the surface of standard parts. Some standard parts, such as drill tail screws, require a relatively hard surface layer, so heat treatment can be performed on the drill tail screws to ensure that the drill tail screws have sufficient hardness. This is the reason for the heat treatment.
3. The mechanical plating of the standard parts is to allow the metal particles to be cold-welded to the standard parts to ensure some effects on the surface of the standard parts. Mechanical plating and electroplating are basically similar, but the methods we use are different, and the results can be said to be the same.
4. To passivate the surface of standard parts, passivation mainly has two functions, one is to strengthen the hardness of standard parts, and the other is to greatly reduce the oxidation of standard parts. When carrying out the surface treatment process of fasteners, we can choose the most appropriate method according to the specific situation. In this way, the fastener can play a better role in use.
