連続無酸化雰囲気炉による工業用純チタンのろう付

抄録

Joining technology of CP-Titanium, capable of providing precision joining, is industrially very useful; however, it still has some unsolved problems in continuous atmosphere brazing technology. In this study, commercial pure titanium was brazed with laminated brazing fillers by using a newly developed continuous type non-oxidizing atmosphere furnace. This new furnace, using inert gas without hydrogen, is capable of providing oxygen partial pressure equal to or lower than that available in a vacuum furnace at a regular atmospheric pressure. Excellent applicability and capability of the new furnace in commercial pure titanium brazing was concluded by a series of evaluations after brazing including microscopic observations of the joint interface, chemical analysis, and shear test.
