Influence of helicon discharge treatment on ensuring adhesive strength of protective PVD coating CrN on brass-based forms of intaglio printing

The influence of the helicon discharge on the formation of the relief and chemical composition of the surface of single phase brass L63 is investigated. Two stages of formation of the structure of the sprayed layer of brass substrate during processing are revealed - smoothing of the surface relief and selective spraying of phase components of brass, which will create a surface with the necessary parameters to increase the adhesion of protective CrN coating..
