HYBRID ARTICLE, METHOD FOR FORMING HYBRID ARTICLE AND METHOD FOR WELDING

A hybrid article (100) is disclosed including a sintered coating (104) disposed on and circumscribing the lateral surface (106) of a core (102) having a core material (108) and a greater density than the sintered coating (104). The sintered coating (104) includes more than 95% up to 99.5% of a first...

Beschreibung
Zusammenfassung:	A hybrid article (100) is disclosed including a sintered coating (104) disposed on and circumscribing the lateral surface (106) of a core (102) having a core material (108) and a greater density than the sintered coating (104). The sintered coating (104) includes more than 95% up to 99.5% of a first metallic particulate material (110) including a first melting point, and from 0.5% up to 5% of a second metallic particulate material (112) having a second melting point lower than the first melting point. A method for forming the hybrid article (100) is disclosed including disposing the core (102) in a die (200), introducing a slurry (204) having the metallic particulate materials (110 and 112) into a gap (202) between the lateral surface (106) and the die (200), and sintering the slurry (204). A method for welding a workpiece (600) is disclosed including the hybrid article (100) serving as a weld filler.
