Essay

Developed new construction of inserted composed tooth. It give an opportunity to increase the tooth-bit joining reliability and to decrease the hard-facing alloy expense. Developed and grounded the method for new teeth formation - the method of vibration mixing. Proposed the new technological method for increasing the tooth-bit joining reliability by fast heating for hardening of rotary bits. Developed and inculcated methods of fracture toughness K1C valuing for hard-facing alloyed teeth.
