Corrosion protection of fasteners
Fasteners are the most common parts in mechanical equipment, and their functions are also very important. However, corrosion of fasteners during use is the most common damage.
Fasteners are the most common parts in mechanical equipment, and their functions are also very important. However, corrosion of fasteners during use is the most common damage. In order to prevent fasteners from occurring during use Corrosion phenomenon, many manufacturers will surface treatment of fasteners after production, which surface treatment methods can improve fasteners to prevent corrosion phenomenon? There are four main surface treatment methods to prevent fastener corrosion phenomenon, We can choose the most suitable method according to the specific situation and needs:
Huasheng fastener products include: internal locking wire drawing rivets, external locking wire drawing rivets, hippocampus rivets, double drum rivets, single drum rivets, lantern rivets, open rivets, pull flower rivets, groove blind rivets, closed rivets, Rivet nuts, pneumatic rivet guns and related fasteners.
Electroplating the standard parts, this method is to put the standard parts into the metal solution, and then cover the surface of the standard parts with a layer of metal through the current. There are many effects on this layer of metal. For example, we can use some different effects Choose some different plating metals, if we want to prevent the standard parts from rusting, then we can galvanize the surface of the standard parts.
2. Mechanical plating
The mechanical plating of standard parts is to cold-weld metal particles to the standard parts, which ensures some functions of the surface of the standard parts. Mechanical plating and electroplating are basically similar, but the method we use is different, and the results can be said to be the same.
3. Heat treatment
For the heat treatment of the surface of the standard parts, there are some standard parts, such as the drill tail screw, which requires a relatively hard surface, so the drill tail screw can be heat treated to ensure that the drill tail screw 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 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 suitable method according to the specific situation. In this way, the fasteners can play a better role in the use process.
