Piston rod seal manufacturers tell you how to improve the corrosion resistance of the piston rod surface
Piston rod, is currently widely used in most mechanical products in a connecting parts, however, due to some mechanical applications of the environment is relatively bad, so the piston rod corrosion resistance also has a relatively high requirements, so we should how to improve the piston rod surface corrosion resistance!

Piston rodAt present, it is widely used in most mechanical products. However, due to the harsh environment of some mechanical applications, there are relatively high requirements for the corrosion resistance of the piston rod, so how should we improve the corrosion resistance of the piston rod surface?Piston rod sealManufacturers tell you the answer!
1. Rolling processing:
Through rolling forming, a layer of cold work hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, and can delay the generation or expansion of fatigue cracks, thereby improving the surface corrosion resistance.
2. Chrome plating:
After chrome plating, the piston rod can have a hard, smooth and corrosion-resistant surface. Therefore, if you want to improve the corrosion resistance of the piston rod surface, you need to go through chrome plating. After chrome plating, the coating hardness of the piston rod can be as high as HV1100, and the coating is smooth, uniform in thickness and strong in dispersion ability, so that it can be greatly improved in some aspects.
3. Quality adjustment:
After tempering treatment, it can effectively improve the working strength of the material, help to close the tiny cracks on the surface, hinder the expansion of erosion, and improve the surface corrosion resistance. However, not all piston rods need to be tempered, so the tempering treatment should be judged according to the actual situation and materials.
AbovePiston rod sealThe content introduced by the manufacturer is a method to improve the corrosion resistance of the piston rod surface. The better the corrosion resistance of the piston rod surface, the easier it is for the piston rod to be less eroded, so that a longer service life can be obtained.
