Method of making a cermet-type alloy
Abstract
Abstract AN IMPROVED CERMET-TYPE ALLOY AND METHOD OF MAKING SAME WHICH IS PARTICULARLY ADAPTABLE FOR FORMING PROTECTIVE SURFACE COATINGS ON HEAT-RESISTANT ALLOYS. A PARTICULATED MIXTURE IS FORMED CONTAINING TITANIUM AND/OR ZIRCONIUM REACTIVE METAL CONSTITUENTS THAT UNDERGOE AN EXOTHERMIC REACTION UPON FUSION AT AN ELEVATED TEMPERATURE IN A SUBSTANTIALLY INERT ATMOSPHERE WITH SILICON AND/OR BORON PRESENT IN THE MIXTURE FORMING THE CORRESPONDING SILICIDES OR BORIDES OF THE REACTED METALS IN SITU WHICH ARE SUBSEQUENTLY PRECIPITATED AS A UNIFORMLY DISPERSED DISCONTINUOUS PHASE IN A CONTINUOUS PHASE OF A NICKEL AND/OR COBALT BASE MATRIX. THE INVENTION ALSO ENCOMPASSES NOVEL POWDER COMPOSITIONS FOR EXOTHERMICALLY FORMING THE CERMET-TYPE ALLOYS AND COATINGS.
