Definitions
- the invention more particularly relates to a flame spray powder mixture containing a self-fluxing alloy powder and a powder of a metal which melts at a high temperature, such as tungsten, rhenium, tantalum, molybdenum, columbium, or alloys thereof, and to a process for flame spraying such powder mixtures at high temperatures to produce dense, coherent coatings which show excellent wear and load-resistant characteristics.
- a high temperature such as tungsten, rhenium, tantalum, molybdenum, columbium, or alloys thereof
- the spray welding process involves the steps of first spraying the powder onto the surface to be coated, using the conventional flame-spray process, and thereafter fusing the coating in place.
- the fusing may be done, for example, in a furnace, by means of induction heating or the like, but is often done by directly heating the coated surface with a heating torch.
- the flame spraying is the sprayweld process is simply a mode of positioning the alloy powder on the surface to be coated in order to allow the fused coating to be formed by the subsequent fusing operation.
- the coating thus sprayed prior to the fusing operation is porous, is not firmly bonded in place, and is not useful in the same manner as subsequent fused coatings, i.e. is not a hard, dense, wear-resistant surface.
- the particles of a groundfinished, as-sprayed coating will for example pull out when pressure-sensitive tape, such as Scotch tape, is applied and then stripped off.
- a further object of this invention is a process for producing dense, wearand load-resistant coatings, utilizing a flame spray powder mixture containing a self-fluxing alloy powder.
- the meal powder which is admixed with the self-fluxing alloy powder preferably should have a melting point above 4000 F., as for example between 4600 and 6200 F.

- the most preferable metal powders are powders of tungsten, tantalum, or molybdenum, or alloys thereof having a melting point between 4600" F. and 6200" F.
- the high melting point metal powder must be a metal per se and cannot be in the form of a refractory oxide, carbide, or the like. Furthermore, the high melting point metal powder must be independent of the self-fluxing alloy powder and may not be alloyed therewith or the like.
