Composites and method for manufacturing same

A composite of a metal matrix with one or more incorporated secondary phases is referred to as a metal matrix composite (MMC). Secondary phase refers to all the particles or fibers which have a different composition than the metal matrix, and which are incorporated therein. As incorporation phases, elements and compounds are possible which, as a result of their material characteristics, are suited for improving individual properties of the metal matrix. Besides an improvement in individual properties of the pure metal matrix as a result of the incorporated secondary phase, certain properties of the metal are also degraded, in particular by particles having a size of 1 to 50 μm. For example, the elongation at break decreases, the strength may decrease, or the tribology may become less favorable. The object of the invention is to improve the properties of the composites by an appropriate selection of the size and type of fibers and/or particles in the secondary phase, and/or the formation of a special pore structure in the preform.

Blade drill bit and method for its manufacture

A drill bit comprises a main body part (11) having a shank (13) for connection to a drill string, an end face, an internal passage (9) for supplying drilling fluid to the end face, a number of blades (15) extending from the end face outwardly and longitudinally of the central axis of rotation of the bit, and a number of cutters (16) mounted on each said blade. Each blade comprises a central metal core at least partly surrounded by solid infiltrated matrix material. A method of manufacturing such a drill bit includes the steps of providing a metal mandrel (17) having said shank and internal passage, and providing on the mandrel, so as to be supported by it, a number of blade cores (22) each having a portion extending outwardly and longitudinally of the central axis of the mandrel, casting infiltrated matrix material (23) around at least a part of each core (22) and around at least a part of the mandrel (17) to form the blades, and then removing portions of the cores (22) so as to detach each core from support by the mandrel (17) to leave within each blade a core (22) which is substantially wholly supported by the surrounding matrix material (23).
