The fabrication of the target cathode, the selection of its chemical composition, and the establishment of the optimal heating temperature to minimize the formation of the droplet phase are important conditions for obtaining a coating with the desired properties. This article examines the thermal operating conditions of a consumable water-cooled target cathode made of various materials (Al, Cu, Steel 45, Ni, Ti, Mo) in vacuum arc plasma sources. Furthermore, it is necessary to establish the optimal heating temperature of the target cathode and prevent it from overheating, thereby minimizing the formation of the droplet phase. The heating temperature of the target cathode is analyzed. Calculated values of the Biot criterion are presented to confirm the hypothesis of uniform temperature distribution across the cathode thickness. Selecting the optimal target cathode composition and establishing its heating temperature will enable the production of a coating with the desired properties while minimizing the formation of the droplet phase. Such coatings can be used in both medical and industrial applications.
