Abstract: A tool for a high temperature, high pressure apparatus includes a working layer of a first hard metal composition of material and at least one supporting layer of a second hard metal composition of material attached to the working layer. The first hard metal composition has a mean linear intercept of less than about 0.4 μm of a binder phase. The working layer has a top and bottom surface. At least one supporting layer of a second hard metal composition of material is attached to the working layer. The at least one supporting layer includes an upper portion. An interface region is formed by the bottom surface of the working layer and the upper portion of the at least one supporting layer. The bottom surface and upper portion have a corresponding shape, wherein the bottom surface and upper portion are bonded to form the corresponding shape in the interface region.

Abstract: The present disclosure relates to a wear part having high wear resistance and strength and a method of making the same. The wear part is composed of a compound body of cemented carbide particles cast with a low-carbon steel alloy. The low-carbon steel alloy has a carbon content corresponding to a carbon equivalent Ceq=wt % C+0.3(wt % Si+wt % P) of about 0.1 to about 1.5 weight %. The wear part could include a body with a plurality of inserts of cemented carbide particles cast into a low-carbon steel alloy disposed in the body. Each of the plurality of cemented carbide inserts are coated with at least one layer of oxidation protection/chemical resistant material. The plurality of inserts are directly fixed onto a mold corresponding to the shape of the wear part. The cemented carbide inserts are then encapsulated with the molten low-carbon steel alloy to cast the cemented carbide inserts with the low-carbon steel alloy.
