ABSTRACT:
High-pressure high-temperature device for conversion the graphite to diamonds (DCGD) includes a container having a high pressure chamber, an inlet for introducing a fuel, an oxidizer and an electrolyte respectively into container, a generator of instantaneous electro-impulses, electrodes secured to the container and connected with the generator of instantaneous electro-impulses to produce the power electro-discharge between electrodes. DCGD includes a source of a direct electro-current and a pair of positive and negative electrodes positioned within an electrolyte for heating the graphite in the high pressure chamber. The high-pressure chamber includes a cylinder-piston unit submerged within an electrolyte. The piston of cylinder-piston unit is explosively driven toward the high-pressure chamber by the combined action of electro-discharge in the electrolyte a combustion of fuel inside of container. DCGD may be adapted for compaction other materials, for extruding, forging and the like. DCGD may be used also to provide coating, molding and hardening work pieces which must be placed in the container.
