What Are the most common Solenoid Housing/plunger Steel Surface treatments ?

There are many reasons why Solenoid Housing/plunger steel surfaces are treated, from making them more attractive through to protecting them against scratching, peeling, extreme weather and corrosion. Here we take a brief look at some of the most common steel surface treatments utilized nowadays as well as a few of their many benefits. 

The surface treatment of electromagnet parts has a great influence on improving their corrosion resistance, wear resistance and overall appearance. The following are some common surface treatment methods for electromagnet parts:

1.Anti-corrosion coating: 

For electromagnet parts, anti-corrosion coating is key. This can include spraying, brushing or dipping a layer of paint with good anti-corrosion properties, such as anti-rust paint, electrophoretic coating, etc. Anti-corrosion coating helps protect parts from moisture, oxygen and other corrosive substances.

2. Plating treatment:

Galvanizing is a common surface treatment method that forms a protective film of zinc by plating a layer of zinc on the surface of the parts to improve corrosion resistance.

Nickel plating, chrome plating, etc.: Other metal plating can also improve surface hardness, corrosion resistance and aesthetics.

3. Polishing and grinding:

For some electromagnet parts that require a good appearance, polishing and grinding are commonly used surface treatment methods. This helps remove surface flaws, improve surface finish, and increase corrosion resistance.

4. Sandblasting:

Sandblasting is a method of changing the surface morphology of a work piece by impacting it with high-speed flying sand. This can improve surface quality, corrosion resistance, and increase surface adhesion.

5. Anodizing:

Anodizing is a commonly used surface treatment method for parts made of aluminum and its alloys. This method can form an oxide film on the aluminum surface to improve corrosion resistance and hardness

6. Phosphating

Phosphating is a method of forming a phosphide layer on the metal surface to improve surface hardness and corrosion resistance.

7. Heat treatment

Through heat treatment, the crystal structure and hardness of the material can be changed, and the wear resistance and strength can be improved.

When choosing a surface treatment method, factors such as the material of the component, the use environment, functional requirements, and cost need to be considered. The final choice should be made under the joint decision of the engineering and design teams.
