This invention is directed toward a material which is used to coat or create a surface for machine cutting tools, all types of drill bit teeth, saw teeth, bearing surfaces valve seats, nozzles and the like, thereby producing surfaces which are highly abrasion and erosion resistant. Furthermore, this invention includes some of the possible methods for producing such a material given that the methods and apparatus required provide a significant cost reduction over those required for producing prior art surface materials with similar abrasion and erosion resistant properties. More specifically, the material set forth can be formed at relatively low temperatures and relatively low pressures by sintering mixtures for a relatively short period of time.
