Title:
BRAZE MATERIALS, BRAZING PROCESSES, AND COMPONENTS WITH WEAR-RESISTANT COATINGS FORMED THEREBY
Document Type and Number:
WIPO Patent Application WO/2013/115887
Kind Code:
A3
Abstract:
Braze materials, brazing processes, and coatings produced therefrom, for example, a wear-resistant coating suitable for protecting surfaces subjected to wear at high temperatures. The braze material includes first particles formed of a metallic alloy and second particles formed of a cobalt-base braze alloy having a melting point below the melting point of the first particles. The braze alloy consists of, by weight, 3.5 to 15.0% silicon, 2.0 to 6.0% boron, and the balance cobalt and incidental impurities, and the second particles constitute at least 30 up to 90 weight percent of the first and second particles combined. Following a brazing cycle performed on the braze material, a wear-resistant coating is formed in which the first particles are dispersed in a matrix of the braze alloy.
