1. Способ получения пористых и пористо-компактных изделий из быстрозакаленных порошков титана и его сплавов, включающий наводороживание, спекание в вакууме и охлаждение до комнатной температуры, отличающийся тем, что процесс спекания проводят в 2 этапа, при этом на первом этапе производят засыпку гранул в разборные или цельные формы из стали или стекла, соответствующих форме конечного изделия, производят операцию термического наводороживания при 600-800°С до концентрации 0,1-1 масс. %, осуществляют вакуумный отжиг при 600-800°С в течение 30-120 минут, затем разрушают или разбирают формы, переносят полученный подспеченный полуфабрикат изделия в вакуумную печь, и осуществляют второй этап спекания при 900-1200°С в течение 30-120 минут.1. A method of obtaining porous and porous compact products from rapidly quenched powders of titanium and its alloys, including hydrogenation, sintering in vacuum and cooling to room temperature, characterized in that the sintering process is carried out in 2 stages, the granules being filled in the first stage in collapsible or integral forms of steel or glass, corresponding to the shape of the final product, perform the operation of thermal hydrogenation at 600-800 ° C to a concentration of 0.1-1 mass. %, vacuum annealing is carried out at 600-800 ° C for 30-120 minutes, then the molds are destroyed or disassembled, the resulting sintered semi-finished product is transferred to a vacuum oven, and the second sintering stage is carried out at 900-1200 ° C for 30-120 minutes . 2. Способ по п. 1, отличающийся тем, что в форму для наводороживания предварительно помещают компактный образец из титана или его сплавов, после чего производят засыпку гранул.2. The method according to p. 1, characterized in that a compact sample of titanium or its alloys is preliminarily placed in a form for hydrogenation, after which granules are filled up.
