摘要： Methods of forming bit bodies for earth-boring bits include assembling green components, brown components, or fully sintered components, and sintering the assembled components. Other methods include isostatically pressing a powder to form a green body substantially composed of a particle-matrix composite material, and sintering the green body to provide a bit body having a desired final density. Methods of forming earth-boring bits include providing a bit body substantially formed of a particle-matrix composite material and attaching a shank to the body. The body is provided by pressing a powder to form a green body and sintering the green body. Earth-boring bits include a unitary structure substantially formed of a particle-matrix composite material. The unitary structure includes a first region configured to carry cutters and a second region that includes a threaded pin. Earth-boring bits include a shank attached directly to a body substantially formed of a particle-matrix composite material.

摘要： The present invention relates to a hard and wear-resisting probe and manufacturing method thereof, and particularly relates to a hard and wear-resisting probe comprising tungsten steel (WC) and manufacturing method thereof. This hard and wear-resisting probe is substantially made of a tungsten steel with high hardness and wear resistance so that the probe is difficult to be worn and the lifetime of the probe is longer. Furthermore, the frequencies for changing the probe and the cost of testing are reduced, and the testing efficiency can be improved.

摘要： A camshaft journal and method of producing the same. The method uses dynamic magnetic compaction in conjunction with austenitic manganese steel powder metal precursors. Journals formed along the camshaft are configured to cooperate with complementary bearing surfaces, and can be used in cooperation with one or more sensors such that the journal does not magnetically interfere with signals travelling to such sensors. The journals may also be subjected to machining, sintering or both once the dynamic magnetic compaction has been completed.

摘要： A powder metallurgy method for making valve guides for use in internal combustion engines advantageously utilizes uniaxial side pressing to form compacts. Such compacts are subsequently sintered, formed into a cylindrical shape, and then hollowed to form a valve guide. The valve guides exhibit improved uniformity and density and hardness from end to end of the valve guide when contrasted to powder metal valve guides formed with uniaxial end pressing.

摘要： A threaded nozzle for use in a cutter bit is disclosed. Threads are either machined into or pressed into a pressed powder nozzle then the nozzle is sintered. Threads of the nozzles of the present invention exhibit improved hardness and have a rougher surface finish than threads machined post-sintering. Shaping of the threads into the nozzle before sintering is also more economical and efficient than post-sintering machining.
