Technology for producing new wear-resistant coatings in the plasma of a vacuum-arc discharge

In this paper obtaining of hardening coatings formed by periodic deposition of thin layers of refractory compounds from plasma of vacuum-arc discharge is discussed. Studies have shown that the quality and structure of the formed multi-layer coating is determined by the initial layer of the material on the processed substrate, depending on the deposition conditions and primarily on the temperature of the product. It was obtained that by cleaning plasma flux from the droplet formation and varying process parameters it is possible to effectively control the composition and structure of the formed coating.
