Glow discharge as a heat source for bonding and brazing processes (Review)
G.P. Bolotov
Chernigiv State University of Technology, Chernigiv, UkraineAbstract
Main results of research and development aimed at improvement and widening of technological capabilities of glow discharge as a heat source for joining processes are presented. Methods which hold promise for increasing stability of glow discharge are described and basic types of power supplies and pieces of equipment are characterized. Technological problems which are successfully solved by glow-discharge bonding and brazing are outlined.
Keywords: diffusion bonding, brazing, glow discharge, stability, power supplies, equipment, application field
