Work is directed on reception the modified superfirm powder materials for working elements of drilling technics. It is carried out the complex research of modifying ultradisperse powder additives including thermal, X-ray structural and X-ray spectral analyses; moisture content and other impurity is revealed. Analytical research of element structure, microstructure and microhardness of superfirm alloy of drilling technics working element is carried out. On the basis of the lead researches the modified powder struc-tures of which pre-production models of wearproof drilling plates are made are developed and prepared.
