BRAZING FILLER METAL FOR JOINING ZIRCONIA AND STAINLESS STEEL

摘要

PURPOSE:To form a joined part having substantial heat resistance and high toughness by using a brazing filler metal formed by incorporating a specific ratio each of Ni, Mn, B and Ag into Zr to join zirconia and stainless steel. CONSTITUTION:The brazing filler metal consisting, by weight %, of 10-35% Ni, 0.5-5% Mn, 0.1-1.0% B, 0.5-5% Ag and the balance Zr is prepd. The stainless steel and zirconia are butted by using such brazing filler metal and are heated to melt the brazing filler metal in a vacuum or reduced atmosphere contg. a small amt. of inert gas, by which the stainless steel and zirconia are joined.
