The best way to deal with the corrosion of fasteners


Fasteners are the most common parts of machinery and equipment, which is very important, however,in the use of fasteners corrosion is one of the most common damage, in order to prevent the use of fasteners in the process of occurrence Corrosion phenomenon, many manufacturers in the production of fasteners will be its surface treatment, which surface treatment can increase the fastener to prevent corrosion phenomenon? There are four kinds of surface treatment can prevent the occurrence of corrosion of fasteners, We can according to the specific needs of the most appropriate way to choose:

First, electroplate

   Electroplating the standard parts, this method is to put the standard parts into the metal solution, and then through the current to the surface of the standard parts covered with a layer of metal, the role of this layer of metal there are many, for example, we can according to some different effects Choose some different coating metal, if we want to prevent the standard parts rust, then we can in the standard parts of the surface plating zinc.

Second, mechanical plating

    The standard parts for mechanical plating, is to allow the metal particles for cold parts of the standard parts to ensure that the standard parts of the surface of some of the role. Mechanical plating with the plating are basically similar, but we use the method is not the same, the results can be said to be the same.

Third, heat treatment

    For the standard parts of the surface heat treatment, there are some standard parts, such as drilling screws need to be more hard surface, so you can heat treatment the drilling screw to ensure that the drilling screw has enough hardness. This is the reason for the heat treatment.

Fourth, the surface passivation

    For the standard parts of the surface passivation, passivation has two main roles, one role is to strengthen the hardness of standard parts, the another effect is can role that can make the standard parts of the oxidation greatly reduced. In the fastener surface treatment process, we can choose the most suitable method according to specific circumstances demand. So that the fastener in the use of the process to play a better role
