    • A tool for a high temperature, high pressure apparatus includes a working layer (20) of a first hard metal composition of material and at least one supporting layer (24) of a second hard metal composition of material attached to the working layer (20). The first hard metal composition of the working layer (20) has a mean linear intercept of less than 0.4um of a binder phase. The working layer (20) has a top (16) and bottom (18) surface. At least one supporting layer (24) of a second hard metal composition of material is attached to the working layer (20). The at least one supporting layer (24) includes an upper portion. An interface region (30) is formed by the bottom surface of the working layer (18) and the upper portion of the at least one supporting layer (24). The bottom surface (18) and upper portion have a corresponding shape, wherein the bottom surface (18) and upper portion are bonded to form the corresponding shape in the interface region (30).
    • 用于高温高压设备的工具包括第一硬质合金材料组合物的工作层(20)和连接到工作层(20)的材料的第二硬金属组合物的至少一个支撑层(24) 。 工作层(20)的第一硬金属组合物具有小于0.4μm的粘结相的平均线性截距。 工作层(20)具有顶部(16)和底部(18)表面。 第二硬质合金材料组合物的至少一个支撑层(24)附着到工作层(20)。 所述至少一个支撑层(24)包括上部。 界面区域(30)由工作层(18)的底表面和至少一个支撑层(24)的上部形成。 底表面(18)和上部具有相应的形状,其中底表面(18)和上部分在接合区域(30)中结合形成相应的形状。
