The ways to enhance the surface performance of precision piston rods

What are the ways to enhance the surface performance of precision piston rods?

Methods to enhance the corrosion resistance of product surfaces:

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 enhancing the surface corrosion resistance. .

2. The chrome-plated precision piston rod can have a hard, smooth and corrosion-resistant surface after being chrome-plated. After chrome plating, the coating hardness of the product can reach HV1100, and the coating is smooth, uniform in thickness and strong in dispersion.

3. After quenching and tempering, it can enhance the working strength of the material, help to seal the tiny cracks on the surface, hinder the expansion of erosion, thereby enhancing the corrosion resistance of the surface. However, not all of them need to be tempered, so the treatment of tempering should be judged according to the actual situation and materials.
