Improve the corrosion resistance of the piston rod surface

How Piston Rods Improve Surface Corrosion Resistance?

1. Rolling processing:

Through roll 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:

The piston rod is chromed for a hard, smooth, corrosion-resistant surface. Therefore, if you want to improve the corrosion resistance of the piston rod surface, it needs to be chrome-plated. After chrome plating, the piston rod has a smooth coating, uniform thickness and strong dispersion ability, which can greatly improve some aspects.

3. Conditioning and tempering:

Quenching and tempering is the quenching and tempering treatment of the piston rod. After the quenching and tempering treatment, the working strength of the material can be effectively improved, which is helpful for the sealing of tiny cracks on the surface and hinders the expansion of the erosion effect, thereby improving the corrosion resistance of the surface. However, not all piston rods need to be quenched and tempered, so the quenching and tempering treatment should be judged according to the actual situation and materials.
