Fasteners are the most common components in mechanical equipment and play a crucial role. However, corrosion during use is the most common type of damage to fasteners. To prevent corrosion during use, many manufacturers perform surface treatments after production. What surface treatments can improve corrosion prevention in fasteners? There are four main surface treatments to prevent corrosion in fasteners. We can choose the most suitable method based on specific needs:
Huasheng fastener products include: internal locking drawn rivets, external locking drawn rivets, seahorse rivets, double-drum rivets, single-drum rivets, lantern rivets, open-type rivets, drawn rivets, grooved pull-core rivets, closed-type rivets, rivet nuts, pneumatic rivet guns and related fasteners.
I. Electroplating
Electroplating standard parts involves placing them in a metal solution and using an electric current to coat the surface with a layer of metal. This layer has many functions; different plating metals can be chosen based on different needs. For example, to prevent rust, zinc can be electroplated onto the surface.
II. Mechanical Plating
Mechanical plating of standard parts involves cold welding metal particles onto the surface, ensuring certain surface properties. Mechanical plating is similar to electroplating, but the methods differ; the results are essentially the same.
III. Heat Treatment
Heat treatment of the surface of standard parts is used for parts like self-drilling screws that require a hard surface. Heat treatment ensures sufficient hardness. This is the reason for heat treatment.
IV. Surface Passivation
Surface passivation of standard parts has two main functions: increasing hardness and significantly reducing oxidation. When performing fastener surface treatment, the most suitable method can be chosen based on specific needs. This allows fasteners to perform better during use.
