Abstract
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.

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.
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 metal or powder cobalt-based alloy to provide a sintered cobalt-based alloy cladding metallurgically bonded to the metallic substrate, wherein the powder cobalt-based alloy is of composition 31-35 wt. % chromium, 16-20 wt. % molybdenum, 1-3 wt. % carbon, 0.15-0.45 wt. % boron, up to 1 wt. % manganese, up to 0.7 wt. % silicon and the balance cobalt.
