Information × Registration Number 0212U006158, 0109U000583 , R & D reports Title Development of scientifically-technological bases of forming of structure of diamond granules and technology of their sintering is on the working surfaces of drilling tools in quality of wearproof cutting and recuperative elements; development of cutter of rotatory type of capable effectively to destroy roks with strength of 100-120 МPа; creation of new modifications of diamond-hard-alloy chisels (PDC) is with an increase height of diamond layer. popup.stage_title Head Maystrenko Anatoliy Lvovich, Доктор технічних наук Registration Date 24-02-2012 Organization V.Bakul Institute for Superhard Materials popup.description2 The technological process of forming of multi-layered is worked out diamond - hardalloy granules, the adhesive bond of diamond grains with a hard-alloy shell and high porosity that provides infiltration for it of liquid metallic phase of copula are formed in that ; Worked out technology of production of diamond - hardalloy granules for the use with different metallic copulas in the drilling tools of the different setting. It is experimentally confirmed, that the worked out technology sintering of granules and composites is on their basis, keeps strength of diamond grains on a initial levels; The worked out new construction of hard-alloy cutter of circulating type is with a discrete pin surface for destruction of roks, in basis of that the fixed principle of friction of rolling instead of friction of skidding that allowed cardinally to bring down a temperature in the zone of contact of instrument with a breed and to bring down intensity of his wear the same. It is experimentally shown that energy of destruction of roks by the cutter of this type in 1,3-1,4 times less than, than at cutter with conical insertions (RP-221, RP-207, RТ-32). Unlike radial cutter as РБ-224 speeds of wear of the worked out cutter in 7,6 раза are less; Created diamond-hardalloy plates (PCD: АТП-Б R1304 - 17) with a megascopic thickness up to 1,7 mm of diamond layer. Experimental PDC with the megascopic thickness of diamond layer have wearproofness in 2 times anymore than serial PDC. Drilling cutter of РШ-140Е is equipped by the created PDC plates of АТП-Б R1304 - 17 with the megascopic thickness of diamond layer a to 1,7 mm in productive tests showed firmness in 3,1 times and in 1,5 times drilling speed in comparing to the serial cutters; Worked out three-dimensional model of forms stream of heat in the zone of contact of executive tool with the plates of coloured metals in the process of their welding by a FSW. Calculation distributions of temperature are got in the zone of welding of package. Product Description popup.authors Бежинар М.П. Беспалов С.Ф. Богданов Р.К. Бологова Л.М. Бондарь І.В.
