Using physical vapor deposition to optimize surface properties

Thin film cathodic arc PVD coatings have excellent commercial potential for a number of markets, as they enable surface properties to be modified and optimized independent of the material’s bulk performance. However, many cathodic arc processes suffer from the presence of defects within the coating thickness, limiting commercial application. The arc plasma acceleration process reduces the size and number of macroparticles and other defects in the coating. This process should open up new applications and markets for PVD coatings, including corrosion protection, wear resistance, reduction of die lubrication, and life extension of forming tools. © 2018, ASM International.
