Easily measured metrics that could assign quantifiable values to coating batches for quality control have started to be developed. High-density is an attribute of quality films. Increased density results in harder, more wear resistant coatings in inert and humid environments. Denser films are more resistant to oxidation from aging, limiting the severity and depth of oxide into the coating. Future work includes using metrics for quality. The next step is to develop in house deposition capabilities to develop process-structure relationships.
