Abstract
Настоящее изобретение относится к металлургии и, главным образом, к способам упрочняющей обработки окончательно изготовленных стальных деталей машин и инструментов без изменения их первоначальных размеров и структуры. Для повышения долговечности высокоточных стальных изделий и инструментов после подготовки их поверхности проводят гидрохимическую обработку в течение 40-100 мин в кипящей вододисперной среде, содержащей нанооксид олова, марганца, кремния, свинца, кобальта, никеля, алюминия, молибдена, цинка, сурьмы, ванадия, висмута, бора, бериллия, циркония, железа, хрома, вольфрама, титана или меди с концентрацией 0,5-50 г/л и поверхностно-активного вещества (глицерина) с концентрацией 0,5-50 г/л с добавкой в эту среду щелочи в виде легко испаряемого водного аммиака для поддержания щелочного состояния среды (pH>7), а затем нагревают изделия в воздушной среде при температуре 140-200°C. В результате такой обработки в стальных изделиях создается композиционная структура при реализации двойственного характера упрочнения: (1) на поверхности осаждается нанооксидное твердосмазочное покрытие с очень низким коэффициентом трения и (2) в подслое формируется зона повышенных напряжений сжатия, сравнимых с уровнем напряжений, получаемых методами поверхностной пластической деформации, что существенно повышает работоспособность быстроизнашиваемых стальных изделий.
