Abstract
A metal composition usable as a brazing material for bonding a metal to a non-oxide ceramic. The brazing material contains, at least, one or more metals selected from a first group of transition metals consisting of Pt, Pd, Rh, Ir, Ru and Os, and one or more metals selected from a second group of transition metals consisting of Cr, Mn, Fe, Co, Ni and Cu. The material may further contain one or more elements selected from a third group of elements consisting of B, C, Si and P.
Claims17
A bonded structure, comprising:
- a non-oxide ceramic member bonded by brazing to a metal or another non-oxide ceramic member by a metal brazing composition consisting of at least one or more metals selected from a first group of transition metals consisting of Pt, Pd, Rh, Ir, Ru and Os;
- and one or more metals selected from a second group of transition metals consisting of Cr, Mn, Fe, Co, Ni and Cu, the content of said metal or metals selected from said first group of transition metals ranging between 2 mol % and 70 mol %, while the content of said metal or metals selected from said second group of transition metals ranging between 30 and 98 mol %.
A bonded structure, comprising:
- a non-oxide ceramic member having a metalized layer bonded on a surface thereof by a metalizing composition consisting of at least one or more metals selected from a first group of transition metals consisting of Pt, Pd, Rh, Ir, Ru and Os;
- and one or more metals selected from a second group of transition metals consisting of Cr, Mn, Fe, Co, Ni and Cu, the content of said metal or metals selected from said first group of transition metals ranging between 2 mol % and 70 mol %, while the content of said metal or metals selected from said second group of transition metals ranging between 30 and 98 mol %.
A bonded structure, comprising:
- a non-oxide ceramic member bonded by brazing to a metal or another non-oxide ceramic member by a metal brazing composition consisting essentially of one or more metals selected from a first group of transition metals consisting of Pt, Pd, Rh, Ir, Ru and Os, one or more metals selected from a second group of transition metals consisting of Cr, Mn, Fe, Co, Ni and Cu, and one or more elements selected from a third group of elements consisting of B, C, Si and P.
