Cladded articles and methods of making the same

摘要

In one aspect, methods of making cladded articles are described herein. A method of making a cladded article, in some embodiments, comprises disposing over a surface of a metallic substrate a sheet comprising organic binder and powder metal or powder alloy having a solidus temperature at least 100° C. less than the metallic substrate and heating the powder metal or powder alloy to provide a sintered metal or sintered alloy cladding metallurgically bonded to the metallic substrate.

1. A method of making a cladded article comprising:
disposing over a surface of a metallic substrate a sheet comprising organic binder and powder cobalt-based alloy having a solidus temperature at least about 100° C. less than solidus temperature of the metallic substrate; and heating the powder cobalt-based alloy to provide a substantially fully dense sintered cobalt-based alloy cladding metallurgically bonded to the metallic substrate, the sintered cobalt-based alloy cladding comprising 5-35 wt. % chromium, 0-35 wt. % tungsten, 0-35 wt. % molybdenum, 0-20 wt. % nickel, 0-25 wt. % iron, 0-2 wt. % manganese, 0-5 wt. % silicon, 0-5 wt. % vanadium, 0-4 wt. % carbon, 0-5 wt. % boron and the balance cobalt.
