141 COMPOSITE CERMET ARTICLE EP95938987.5 1995-10-30 EP0800428B1 2000-04-12 MASSA, Ted R.; VAN KIRK, John S.; CONLEY, Edward V.
Methods for making, methods for using and articles comprising cermets, preferably cemented carbides and more preferably tungsten carbide, having at least two regions exhibiting at least one property that differs are discussed. Preferably, the cermets further exhibit uniform or controlled wear to impart a self-sharpening character to an article. The multiple-region cermets are particularly useful in wear applications. The cermets are manufactured by juxtaposing and densifying at least two powder blends having different properties (e.g., differential carbide grain size or differential carbide chemistry or differential binder content or differential binder chemistry or any combination of the preceding). Preferably, a first region of the cermet comprises a first ceramic component having a relatively coarse grain size and a prescribed binder content and a second region, juxtaposing or adjoining the first region, comprises a second ceramic component, preferably carbide(s), having a grain size less than the grain size of the first region, a second binder content greater than the binder content of the first region or both. These articles have an extended useful life relative to the useful life of monolithic cermets in such applications as, for example, wear. The multiple region cermets of the present invention may be used with articles comprising tools for materials manipulation or removal including, for example, mining, construction, agricultural, and metal removal applications.

An earth-boring bit has a bit body and at least one cutter rotatably secured to the bit body. The cutter has a cutter shell surface including a gage surface and a heel surface. A plurality of cutting elements inserts are arranged in generally circumferential rows on the cutter. At least one scraper cutting element is secured at least partially to the heel surface of the cutter. The scraper cutting element includes an outermost surface, generally aligned with the gage surface of the cutter, that defines a plow edge or point for shearing engagement with the sidewall of the borehole while redirecting cuttings up the borehole.

@ A self-sharpening rotary drag bit assembly in which a carrier body adapted to be rotated about a first axis, has a drilling end and carries cutters to be exposed for cutting at the drilling end of the body, the cutters having thereon layers of hard materials defining cutting edges to engage and cut the drilled formation as the body rotates, the cutters also including reinforcement material supporting the layers to resist deflection thereof under cutting loads. The reinforcement material, which is less hard the and the cutting lauers, and the body which is less hard than the reinforcement material, are abradable by the formation as the bit drilling end rotates in engagement with the formation. Thus the cutting edges are soft sharpening as the bit wears away.

PURPOSE: A vertical soil sampler is provided to accurately and effectively analyze various data about the physical and chemical properties and structures of soil by sampling soil samples in original structures of the soil without distortion because the soil samples are not compressed and twisted. CONSTITUTION: A vertical soil sampler comprises a hollow outer tube, a hollow inner tube(100), and hollow soil sampling tube. The outer tube comprises a rotary blade(210) formed in the outer circumference thereof. The inner tube is located inside the outer tube and is connected to the outer tube by bearings(110). The inner tube receives only vertical force of the outer tube because the inner tube is not rotated even through the outer tube rotates. The soil sampling tube is inserted inside the inner tube and collects the soil. The soil sampling tube is longer than the inner tube and has a through-hole for fitting a bar at the top thereof so that the soil sampling pipe can be removed from the inner tube.

The present invention provides a superhard polycrystalline diamond or diamond-like element with greatly improved resistance to thermal degradation without loss of impact strength. Collectively called PCD elements, these elements are formed with a binder-catalyzing material in a high-temperature, high-pressure process. The PCD element has a plurality of partially bonded diamond or diamond-like crystals forming at least one continuous diamond matrix, and the interstices among the diamond crystals forming at least one continuous interstitial matrix containing a catalyzing material. The element has a working surface and a body, where a portion of the interstitial matrix in the body adjacent to the working surface is substantially free of the catalyzing material, and the remaining interstitial matrix contains the catalyzing material. This translates to higher wear resistance in cutting applications, higher heat transfer capacity in heat sink applications, and has advantages in numerous other applications including hollow dies, indentors, tool mandrels, and wear elements.
