Beschreibung
Zusammenfassung:	FIELD: metal processing.SUBSTANCE: invention relates to thermal hydrogen processing of semi-fabricated products from porous material based on titanium and its alloys for medical implants. Method involves thermal diffusion saturation with hydrogen and vacuum annealing. Thermal diffusion saturation with hydrogen is carried out at temperature of 700-900 °C to hydrogen concentration of 0.2-0.4 wt%, and then at temperature of 500-650 °C to hydrogen concentration of 0.5-0.9 wt%. Vacuum annealing is carried out at 550-700 °C to hydrogen concentration of not more than 0.01 wt%.EFFECT: higher strength of porous material due to increased share of physical fibers contacts between each other.1 cl, 2 ex Изобретение относится к термоводородной обработке полуфабрикатов и изделий из пористого материала на основе титана и его сплавов для медицинских имплантатов. Способ включает термодиффузионное насыщение водородом и вакуумный отжиг. Термодиффузионное насыщение водородом ведут при температуре 700-900°С до концентрации водорода 0,2-0,4 мас.%, а затем при температуре 500-650°С до концентрации водорода 0,5-0,9 мас.%. Вакуумный отжиг ведут при температуре 550-700°С до концентрации водорода не более 0,01 мас.%. Обеспечивается повышение прочностных характеристик пористого материала за счет увеличения доли физических контактов волокон между собой. 2 пр.
