Wear rate of the pure AKTM was higher than a 2.34 - 14.4 times, depending on the version equipping the diamond hybrid material. When working elements of rock cutting AKTM observed fracture pattern characteristic of the grinding process. When working rock cutting elements made of material "gibridayt" observed fracture pattern characteristic of the cutting process. Heat treatment in a muffle furnace in a stream of argon at T = 1150 ° C has a positive effect on the wear resistance of elements of rock cutting gibridayta - it increases to 2.5-5.5 times, the stress is removed from inserts CVD-diamond. Developed and patented in Ukraine and Russia experienced design bits type BT-22 76 mm diameter, equipped with inserts of Gibridayt and synthetic diamonds. Production testing while drilling in hard rock IX - XI category show that bits of the type BT-22 serial bits exceed BS-06 on average 1.52 times in meterage, and on mechanical drilling speed of 1.4 times. Impregnated in vacuum samples KAM additionally structured carbide granules VK6, have a more perfect structure. The structure of the metal composition of the matrix is more dense, through better distribution of metal bond in composite materials with a metallic matrix. Found that doping microadditives VC ensure maximum preservation of the original grain size of the carbide component carbide sintering pellets and increase their failure load in compression and microhardness. Use as a wear-resistant filler new compounds (chemical vapor carbidization monocarbide tungsten carbide pellets and VK6 doped carbide VC) opens the possibility of using technological methods to control durability of composite diamond rock cutting tool materials for the most efficient drilling of rocks with different physical and mechanical properties. The use of such fillers possible to increase the average penetration rate and durability of diamond drill bits. Product Description popup.authors Ільницька Г.Д. Александрова Л.І. Богданов Р.К.
