摘要： 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.
