FIELD: mining.
SUBSTANCE: group of inventions relates to reinforced impregnated matrix downhole tool, method of its reinforcement, as well as to reinforced impregnated matrix drill bit. Reinforced impregnated matrix downhole tool includes housing, containing carbide material and copper or copper alloy impregnating binding material; blade made integral with housing and made from same materials as housing, and extending approximately from one housing end in direction of housing second end, wherein blade comprises leading edge, trailing edge and surface extending from leading edge to trailing edge; at least one cutter installed on said surface; intermediate priming coating connected with leading edge and/or said surface and being chromium-nickel alloy, containing one or more reducing substances; and reinforcing material, connected with at least part of intermediate priming coating, in which intermediate priming coating is attached to blade and with reinforcing material.
EFFECT: technical result consists in reduction of wear due to application of reinforcing material.
