摘要： A superindurate, texturally stable abrasive composite material useful in the making of cutting and abrading tools, such as oil well drills, industrial metal cutting bits, mills, planar knives and abrasive grinders. The superficies of the object tool is comprised of the outer face of a tough matrix material and the projecting ends of a preferentially oriented indurate fibers or filaments, such as boron or the indurate intermetallic compounds of boron endowed with a hardness closely approaching that of industrial diamonds, which have been dispersed in collocated array and embodied within a tough matrix material such, for example, as in a sponge iron matrix which has been briquetted in the configuration of the object tool and then heated at temperatures sufficient for incipient fusion to occur to form the composite tool. Other ductile metals such as aluminum, nickel and cobalt, including certain of their alloys, together with steel and titanium are further examples of matrix materials which may be employed. The indurate filaments are so dispersed and collocated that the outer ends of the fibers or filaments are aligned normal to the tool''s work-taction surface and consequently to the surface of the object material to be cut or abraded.

摘要： A super-indurate, texturally stable abrasive composite material useful in the making of cutting and abrading tools, such as oilwell drills, industrial metal cutting bits, mills, planer knives and abrasive grinders. The superficies of the object tool is comprised of the outer face of a tough matrix material and the projecting ends of a preferentially oriented indurate fibers or filaments, such as boron or the indurate inter-metallic compounds of boron endowed with a hardness closely approaching that of industrial diamonds, which have been dispersed in collocated array and embodied within a tough matrix material such, for example, as in a sponge iron matrix which has been briquetted in the configuration of the object tool and then heated at temperatures sufficient for incipient fusion to occur to form the composite tool. Other ductile metals such as aluminum, nickel and cobalt, including certain of their alloys, together with steel and titanium are further examples of matrix materials which may be employed. The indurate filaments are so dispersed and collocated that the outer ends of the fibers or filaments are aligned normal to the tool''s work-taction surface and consequently to the surface of the object material to be cut or abraded.

摘要翻译： 用于制造切削和研磨工具（如油井钻头，工业金属切削钻头，磨机，刨刀和磨料磨床）的超级凹凸不平，结构稳定的磨料复合材料。 目标工具的外观由韧性基体材料的外表面和优先取向的无定形的无定形纤维或细丝的突出端组成，例如硼或硼的凹入金属间化合物，其硬度接近于 工业钻石已经分散在配置阵列中并体现在坚韧的基质材料中，例如在已经被压块成对象工具的构造中的海绵铁基质中，然后在足以初始熔化的温度下加热 形成复合工具。 诸如铝，镍和钴的其它延性金属，包括它们的某些合金，以及钢和钛是可以使用的基质材料的其它实例。 浸渍的长丝如此分散和配置，使得纤维或细丝的外端垂直于工具的工作表面对准，并因此与被切割或磨损的物体表面对齐。
