Abstract
1322670 Arc evaporation apparatus L P SABLEV N P ATAMANSKY V N GORBUNOV J I DOLOTOV V N LUTSENKO V M LUNEV and V V USOV 28 July 1971 35379/71 Heading C7F [Also in Division H1] Vacuum vapour deposition apparatus comprises an anode 26, a cathode 9 of the metal to be evaporated, arranged on cooling bed 8 and facing the anode, means 6 for maintaining a vacuum, an arc current source 40 connectable between anode 26 and cathode 9, a trigger electrode 29 arranged to generate an electric arc cathode spot on the evaporation surface of the cathode, and means, such as shield 21, for extinguishing the cathode spot when it displaces from the evaporation surface to a non-evaporation surface of the cathode. The anode may be a cylindrical or spherical envelope within chamber 2, or may be the chamber itself, Fig.9 (not shown) or the substrates may constitute the anode, Figs.6, 7, and 8 (not shown). The substrate(s) 13 may be individual plates, or a moving metal band, Fig.4 (not shown); the cathode evaporation surface may be a flat disc or ring, or the inside or outside of a cylinder (for coating the outside or inside respectively of a tube); cooling is by circulation of a cooling liquid via nipples 19 and space 17 or by provision of an external heat sink, Fig. 3 (not shown), and automatic control of trigger electrode 29 is achieved using various described circuits. Metals which may be evaporated are Pb, Sn, Zn, Cr, Cd, Nb, Mo, Ta, Ti and W.
