Vacuum arc discharge is used for formation of pure metal and complex combined coatings, and also for the impact of the discharge on a surface to remove superficial contaminants. Physical processes observed in an arc discharge are mostly determined by the behavior of cathode spots, which are fundamentally unstable plasma formations and are characterized by a certain value of average lifetime. Reliable stabilization of the cathode spots and controlling their movements on the working surface grants the technology a grater importance in application.

“…The reduction of the emission properties of the surface is achieved by forming an antiemission intermetallic coating Pt 3 Zr [8,9]. According to the calculation in the temperature range of vacuum annealing 1000…2000 K in the system ZrC (obtained by evaporation in a plasma of a vacuum arc discharge [10,11]) -Pt (deposited by electroplating) thermodynamically more likely are formed connections Pt 3 Zr -PtZr [12].…”

Summary In this paper the factors influencing the service life of powerful generating lamps are considered. Possibilities of accelerated testing of the devices with the purpose of saving time and resources are described. The methodology and design of the research stand for accelerated testing are presented. Results of a study of the processes of mutual diffusion of the materials of the grid mesh and antiemission coating are shown. Criteria to evaluate the lifetime of the powerful electrovacuum devices are given.

“…The features of generation of arc discharge are determined by the conditions needed for its existence. At the initial moment of time (t 0 ) uncontrolled discharge appears on working surface of the cathode 1 because of the presence of oxide films and dielectric inclusions and covers the entire working surface [7].…”

“…It was found that when the temperature of the cathode increases the lifetime of the discharge on the working surface of the cathode per pulse is reduced. In the meantime the velocity of the cathode spots varies along the length of the cathode [7].…”
