Carbon Steel Nickel plated hollow bushing with four holes for Dipping industrial

Carbon Steel Nickel plated hollow bushing with four holes for Dipping industrial.

Description

The bushing is a matching part used outside the mechanical parts to achieve the functions of sealing, wear protection, etc. It refers to the ring sleeve that functions as a gasket. In the field of valve applications, the bushing is inside the valve cover, and corrosion-resistant materials such as polytetrafluoroethylene or graphite are generally used for sealing.

Nickel plating features
1. The stability of the electroplated nickel layer in the air is very high. Due to the strong passivation ability of metallic nickel, a very thin passivation layer can be quickly formed on the surface.
The membrane is resistant to corrosion by the atmosphere, alkali and certain acids.

2. Electroplated nickel crystals are extremely small and have excellent polishing performance. The polished nickel coating can get a mirror-like gloss appearance, and at the same time.
It can maintain its luster in the air for a long time. Therefore, the electroplated layer is often used for decoration.

3. The hardness of the nickel plating layer is relatively high, which can improve the wear resistance of the surface of the product. In the printing industry, the nickel plating layer is commonly used to increase the hardness of the lead surface.
Due to the high chemical stability of metallic nickel, thicker nickel coatings are also commonly used in some chemical equipment to prevent corrosion by the medium. Electroforming.
Process, used to manufacture electroformed plates, record molds and other molds in the printing industry. The thick nickel-plated layer has good wear resistance and can be used as a Grind the coating.
