Some methods of increasing hot-pressing process efficiency in production of diamond composite materials

The work is directed to increase the technological efficiency of hot-pressing process. The paper describes the solution of the problems of hot-pressing technology, which is still relevant today and is related to the profitability of technology. Based on the analysis of the kinetic equations of hot-pressing processes, the authors identified and experimentally confirmed basic parameters that determine efficiency of the process and quality of the obtained product. Experimental data presented in the paper confirm that the use of specially designed thermal and electrical resistance materials in hot pressure schemes allows significantly to improve sintering conditions. Consequently, the isotropy degree of the composite materials properties is improved throughout its volume. At the same time, the use of the developed thermal insulation materials leads to 70-80% reduction of energy capacity. (author)
