Effects of Composite Nickel-Base Boracic Brazing Filler on the Boride near the Brazing Seam of 316L Stainless Steel

Abstract:

Composite filler（1-x%）BNi-2+ x% BNi-5 with 3 different B content was used to braze 316L stainless steel. The boride near brazing seam was determined by energy spectrum, XRD Micro- area scanning and thermodynamics, dynamics calculation software THERMO –CALC to study the impacts of B content on boride type and quantity. The results showed Cr5B3 and Cr2B were found at and around brazing seam of 1# specimen and Cr2B were found at and around both 6# and 8# specimens. In addition, the Cr2B content of 6 # specimen was greater than 8 # specimen. With the increase of BNi-5 content and decrease of B in the brazing filler, the type and content of the chromium boride reduced.
