Surface treatment is not only about appearance. For many spring applications, coating, plating, passivation, or oil protection can help improve corrosion resistance and working stability.
Common applications
- Outdoor equipment and humid environments
- Medical and electronics applications
- Industrial products requiring corrosion protection
- Mechanisms with friction or noise concerns
Key design inputs
- Operating environment and corrosion risk
- Material type and cleanliness requirement
- Friction, noise, and appearance requirements
- Regulatory or customer-specific standards
Selection notes
Surface treatment should be selected based on the real environment. A low-cost treatment may be enough for indoor products, while demanding applications may require stronger corrosion protection.

FAQ
Does every spring need surface treatment?
No. It depends on material, environment, appearance requirement, and corrosion risk.
Can surface treatment affect spring performance?
Yes. Some treatments may affect friction, thickness, or fatigue performance, so they should be evaluated carefully.
What should be tested after treatment?
Corrosion resistance, appearance, fit, force output, and cycle life should be checked when needed.
