Five Key Processes for Metal Coating

Man in suit coating metalAlthough metal is relatively more durable than other materials, you can enhance the life of metal parts by using a protective coating. The coating will shield the metal surface from corrosion and adhesion. However, critical processes go into metal preparation before applying the coat:

1. Extra Strengthening

Shot peening is a complex process that manufacturers use to increase the strength of metal after applying stress to the surface. The process is like that of using a peen hammer but is more effective and results in faster yields in large-scale applications.

2. Disassembly

Disassembly applies to metal parts that get into the workshop in large components. The parts need to be reduced to pieces before you can use the coating.

3. Cleaning

If the metal surface is dirty, you should first remove the dirt to expose the metal surface; coating dirty surfaces will create bumps in the product. Ultrasonic cleaners and pressure washing are among the standard metal cleaning methods to use here. However, the choice of the cleaners should be right. Otherwise, you will damage the metal, especially if the product will react well to the metal.

4. Stripping

Metals can react to other compounds to create a coating on the surface. This method, therefore, seeks to give a bright metal surface. Failure to remove the existing layer will affect the adherence of the fresh coat to the metal surface.

5. Outgassing

This process is best when working on cast iron or aluminium metal parts, as they can contain foreign products on the metal surface. The process involves placing the metal in a high-temperature oven to melt the oils that can be on the metal structure.

Coating your metal parts improves their functionality and service life. The effectiveness of your coating depends on the quality of the surface, hence the need to hire shot peening services from an expert in metal surface finishing.
