Protection Method Of Partial Nickel Plating

Protection method of partial nickel plating
1. Introduction to partial nickel plating
Local nickel plating refers to nickel plating on local areas of the metal surface. It is usually used in high-wear areas, contact areas, etching areas, etc. that need to protect the metal surface. Partial nickel plating can improve the hardness, wear resistance and corrosion resistance of the material, thereby extending its service life.
2. Surface treatment
Prior to spot nickel plating, the metal surface needs to be properly surface prepared and cleaned. This can help remove surface dirt and oxide layers and achieve good plate adhesion. Common surface treatment methods include:
1> Grinding: Use a grinder or sandpaper to grind the metal surface to remove dirt such as iron oxide layer on the surface.
2> Pickling: Use appropriate pickling solution to clean the metal surface to help remove dirt and oxides from the metal surface.
3>Sand blasting: Use compressed air to spray sand or other particles on the metal surface, similar to grinding, to remove dirt and oxide layers.
3. Coating protection
After local nickel plating is completed, the local area needs to be properly protected by coating to maintain its corrosion resistance and service life. Common coating protection methods include:
1>Coating: Apply a layer of corrosion-resistant paint or paint to the local area to prevent corrosion and wear of the local nickel plated surface.
2> Hardening: Hardening or heat treatment can be carried out in local areas to make the coating harder and more difficult to be worn and corroded.
4. Appropriate usage
In order to ensure that local nickel plating has longer service life and corrosion resistance, attention should be paid to the appropriate use method. Here are some usage suggestions:
1> Avoid excessive wear: Avoid exerting excessive force on the local nickel-plated surface to avoid wear and damage to the plating.
2> Avoid extreme temperatures: Avoid use in high temperature or extremely cold environments to avoid affecting the corrosion resistance of the coating surface.
3> Routine maintenance: Carry out regular maintenance and maintenance to keep the local nickel plating surface clean and dry.
