POWDER BRAZING MATERIAL, JOINED BODY AND VACUUM VESSEL
PROBLEM TO BE SOLVED: To provide a powder brazing material which does not need an atmosphere such as high vacuum, low oxygen concentration, low dew point, a low generated gas and the like and which is excellent in oxidation resistance.SOLUTION: A powder brazing material 100 containing one or more kinds of active metals selected from among titanium (Ti), zirconium (Zr), hafnium (Hf), vanadium (V) and chromium (Cr), silver (Ag) and copper (Cu) and having a layer structure of two or more layers including an active metal core 11 localized with the active metal and an outer shell layer 13, a joined body where a metal member and a member are joined by the powder brazing material and a vacuum vessel are provided.SELECTED DRAWING: Figure 1
【課題】 高真空、低酸素濃度、低露点、低発生ガス等の雰囲気を必要としない、耐酸化性に優れた粉末ろう材を提供する。【解決手段】 チタン（Ｔｉ）、ジルコニウム（Ｚｒ）、ハフニウム（Ｈｆ）、バナジウム（Ｖ）、クロム（Ｃｒ）から選択される一種または二種以上の活性金属と、銀（Ａｇ）と、銅（Ｃｕ）とを含んでなる粉末ろう材１００であって、当該粉末ろう材は、前記活性金属が局在化した活性金属コア１１と外殻層１３とを含む二層以上の層構造を備える粉末ろう材１００、かかる粉末ろう材により金属部材と部材とを接合してなる接合体、並びに真空容器を提供する。【選択図】 図１
