Fasteners are the most common parts of machinery and equipment, the role is also very important, but fasteners in the use of corrosion is the most common kind of damage, in order to prevent fasteners in the use of corrosion phenomenon, many manufacturers in the production of fasteners will be after the surface treatment, which surface treatment can be carried out to improve the prevention of corrosion phenomenon of fasteners?There are mainly four kinds of surface treatment to prevent corrosion of fasteners, we can choose the most appropriate method according to the specific needs of the situation:

Huasheng fasteners products include: internal locking wire rivets, external locking wire rivets, seahorse rivets, double drum rivets, single drum rivets, lantern rivets, open end rivets, blossom rivets, grooved blind rivets, closed type rivets, rivet nuts, pneumatic rivet guns and related fasteners.

I. Electroplating

Plating of standard parts, this method is to put the standard parts into the metal solution, and then through the current so that the standard surface covered with a layer of metal, for this layer of metal has a lot of roles, such as we can choose some different plating metal according to some different roles, we want to prevent the standard parts of the rust, then we can be in the standard parts of the surface layer of zinc plating.

Second, mechanical plating

Mechanical plating of standard parts, is to let the metal particles for standard parts for cold welding, to ensure that the standard parts surface layer of some of the role.Mechanical plating and electroplating are basically similar, only we use different methods, the results can be said to be the same.

Third, heat treatment

For standard parts surface heat treatment, there are some standard parts, such as drill screws need to be relatively hard surface, so you can drill screws for heat treatment, to ensure that the drill screws have sufficient hardness.This is the reason for heat treatment.

Fourth, surface passivation

For standard parts surface passivation, passivation has two main roles, one role is to be able to strengthen the hardness of the standard parts, there is a role is to be able to make the standard parts of the oxidation is greatly reduced.In the fastener surface treatment process, we can look into the specific needs of the most appropriate method.So that fasteners can play a better role in the use of the process.
