Metal surface treatments do a lot more than people often realise. Choosing the right treatment makes a difference, when components are working across industries.
Start with Thorough Preparation
All processes begin with surface preparation. Before applying a coating, the oils, oxides, and other contaminants on the surface of the metal must be removed so that the coating has a suitable surface area to which it can bond. This is usually achieved using grit blasting and/or acid cleaning.
Match the Coating to the Application
All applications are different. Where simplicity and versatility are required then uniform thickness, corrosion resistant, and hard coatings can be applied to a wide variety of surfaces. However, it is essential to select the most appropriate coating for the specific application to avoid potential future problems.

Control Process Parameters Carefully
Getting consistent results comes down to keeping a close eye on things like temperature, timing, and chemistry. Small changes in these areas can affect how thick the coating is, how well it sticks, and how it performs overall.
Inspect and Improve Continuously
It is recommended to measure coating thickness both before and after application to ascertain that coatings are applied within the required limits and to verify compatibility of materials.
Use Proven Application Techniques
With modern spraying and plating methods, it is possible to obtain improvements in the coating coverage and process efficiency. Electrostatic techniques increase transfer efficiency, while controlled immersion processes support even results.
