The Coating Process

 

At Advanced Coating Technologies, we offer coatings for various applications. To ensure the highest quality of our coatings we only use state-of-the-art PVD and CVD technologies and equipment. In general, our coatings are used to reduce wear, friction, and corrosion. A fair amount of knowledge and experience goes into evaluating and choosing the right coating equipment manufacturer, the cleaning process, designing the coating recipes, along with edge preparation and polishing of materials.

The coating process itself takes place in a heated vacuum chamber where gases react with material evaporated from metallic plates to create a molecule that is condensing onto the customer’s pert to form and grow the coating. Most of our coatings are deposited with a thickness between 2-5 microns (1 micron = 0.00004 inch) in a process that takes up to 5-7 hours.

To ensure proper adhesion, the parts to be coated have to be inspected to be free of contaminants like oil and machining residues. Therefore, all parts will be sent through an aqueous cleaning line and drying process. Most common coatings include TiN (Titanium Nitride), TiAlN (Titanium Aluminum Nitride), TiCN (Titanium CarboNitride), CrN (Chromium Nitrde), and other, more advanced, application oriented, and specifically tailored coatings.
