Изобретение относитс к области металл ргии , в частности к способам химико-термической обра ботки изделий из титановых спла .вов, и может использоватьс при разработке технологии обработки дл повышени износостойкости изделий, работающих на трение.The invention relates to the field of metal, in particular, to methods of chemical-thermal treatment of products made of titanium alloys, and can be used in the development of processing technology to improve the wear resistance of products working by friction.
Известен способ химико-термической обработки титана в атмосфере разреженного воздуха при натреве до 800-ЭбО С.The known method of chemical-heat treatment of titanium in an atmosphere of rarefied air when natreva to 800-EbO C.
Однако твердость Яу полученного диффузионного сло не превышает 670 кг/мм, глубина пор дка 30 мк.However, the Yau hardness of the obtained diffusion layer does not exceed 670 kg / mm, the depth is of the order of 30 microns.
С целью увеличени глубины и твердости диффузионного сло насыщение кислородом и азотом воздуха провод т при 1050-10бО°С в течение 20 мин, а затем издели охлаждают со скоростью 150-200°С/час, и весь процесс осуществл ют при остаточном давлении 1 -10 мм рт. ст.In order to increase the depth and hardness of the diffusion layer, the oxygen and nitrogen saturation of the air is carried out at 1050-10 ° C for 20 minutes, and then the products are cooled at a speed of 150-200 ° C / hour, and the whole process is carried out at a residual pressure of 1 - 10 mmHg Art.
В результате на издел х из титановых сплайов получают диффузионный слой глубиной не менее 70 мк, твердостью 1000- 1200 кг/мм, с чистотой, не требующей дополнительной обработки поверхности. Мех.чнические свойства сердцевины обрабатыплемы.х деталей практически соответствуют данным материала в состо нии поставки.As a result, a diffusion layer with a depth of at least 70 microns, a hardness of 1000-1200 kg / mm, with a purity that does not require additional surface treatment, is obtained on titanium splice products. The mechanical properties of the core of the processing of the components. The details practically correspond to the material data in the delivery condition.
Предмет и з о б р е т е и и Subject and d on and e and
Способ химико-термической обработки изделий из титановых сплавов путем диффузионного насыщени их в атмосфере разреженного воздуха, отличающийс тем, что, с целью увеличени глубины диффузионного сло и его твердости, насыщение провод т при 1050-1060°С с последующим охлаждением со скоростью 150-200°С/чйс, и весь процесс осуществл ют при остаточном давлении 1 . рт. ст.The method of chemical-heat treatment of titanium alloy products by diffusion saturation them in an atmosphere of rarefied air, characterized in that, in order to increase the depth of the diffusion layer and its hardness, the saturation is carried out at 1050-1060 ° C, followed by cooling at a speed of 150-200 ° C / number and the whole process was carried out at a residual pressure of 1. Hg Art.
