Films and fractal units under cathode disposal of titanium

Analysis of the processes in the cathode spot of the vacuum arc were carried out. Possibly, these processes lead to the formation and growth of fractal aggregates from arc discharge plasma. The results obtained in the study of the structure of dust particles of the arc discharge plasma underlie the hypothesis. One of the possible reasons for the formation of fractal structures is the occurrence of current sheets and droplet spots when cathode spots approach each other. (paper)
