PROCESS OF METALLIZATION OF ARTICLES Russian patent published in 2003 - IPC

FIELD: technology of coat sputtering, mechanical engineering, deposition of coats on surfaces of metal and nonmetal parts. SUBSTANCE: process of metallization of articles includes sputtering of coat on base with feed of wires connected to power supply source in direction of their crossing, their heating and melting with electric arc excited between ends of wires and sputtering of molten metal by jet of transporting gas. Arc discharge is initiated by contactless high-voltage break-down of gas gap between ends of wires. Heating and melting of wires are carried out by intermittent alternating arc discharge with stabilized value of current, duration and pulse frequency. EFFECT: raised strength of adhesion between coat and base and diminished roughness of sputtered coats. 1 dwg
