Title:
COBALT-CHROMIUM-PALLADIUM-BASED BRAZING ALLOYS
Document Type and Number:
WIPO Patent Application WO1999061195
Kind Code:
A9
Abstract:
This invention relates to brazing metals composed of cobalt-chromium-palladium-based alloys containing transition metals such as cobalt, nickel, tungsten, molybdenum and certain metalloids; and more particularly to multicomponent alloys containing cobalt, chromium, palladium, nickel, tungsten, molybdenum, boron, and silicon, which are especially useful for brazing metals at high temperatures to produce high strength, high oxidation and high temperature and corrosion-resistant brazements. Alloys of the present invention have a composition represented by the formula: Cr>abcdefbal< (plus incidental impurities), where the subscripts "a", "b", "c", "d", "e", and "f" are in atomic percent and "a" is in the range of about 15 and about 22, "b" is between about 0 and about 20, "c" is in the range of about 1 to about 5, "d" is between about 1 and about 10, "e" is in the range of about 5 and about 12, and "f" is between about 5 to about 12 and "bal" is the balance amount to total 100 percent.
