Verfahren zur endformnahen Herstellung von Bauteilen

Final shape production of components made of a material comprising intermetallic phases of trimolybdenum silicide and molybdenum borosilicide homogeneously distributed in a molybdenum matrix, comprises: (a) subjecting a starting powder mixture to a grinding process; (b) producing a suspension with the ground starting powder mixture; (c) introducing the resulting suspension into a metal powder injection molding tool or constructing a green body in layers by screen printing; (d) subjecting the placed green body to thermal and/or chemical treatment; and (e) performing an unpressurized sintering. Final shape production of components made of a material comprising intermetallic phases of trimolybdenum silicide and molybdenum borosilicide homogeneously distributed in a molybdenum matrix, comprises: (a) subjecting a starting powder mixture to a grinding process that comprises at least molybdenum (80 mass), and additionally silicon nitride and boron nitride; (b) producing a suspension with the ground starting powder mixture that comprises at least an organic binder, and exhibits a suitable viscosity for screen printing or for metal powder injection molding; (c) introducing the resulting suspension into a metal powder injection molding tool or constructing a green body in layers by screen printing; (d) subjecting the placed green body to a thermal and/or chemical treatment for expelling the organic components; and (e) performing an unpressurized sintering in a non-oxidizing atmosphere or in high-vacuum conditions at 1600[deg] C.
