Description
Способы диффузионного хромировани и азотировани стали известны .Diffusion chromium plating and nitriding processes have become known.
Новым в предложении вл етс то, что, с целью улучшени эррозионных свойств хромированного сло стальных деталей, азотирование или карбоазотирование осуществл ют при нагреве стальных изделий под закалку . Детали с предварительно нанесенным слоем хрома подвергают нагреву под закалку в атмосфере азота или аммиака в присутствии древесного угл или без него. Нагрев деталей производ т до температуры закалки с выдержкой 40-60 минут, после чего их подвергают закалке в масле или на воздухе.New in the proposal is that, in order to improve the erosion properties of the chrome-plated layer of steel parts, the nitriding or carbonization of nitrogen is carried out by heating steel products for quenching. Parts with a pre-applied layer of chromium are heated under quenching in a nitrogen or ammonia atmosphere, with or without charcoal. The parts are heated to a quenching temperature with an exposure time of 40-60 minutes, after which they are subjected to quenching in oil or in air.
Предмет изобретени Subject invention
1.Способ улуч1иени качества диффузионного хромированного сло аустенитной стали, о т л и ч а ю ш, и йс тем, что, с целью повышени его эррозионной стойкости без снижени прочности основиого металла, хромированный слой подвергают азотированию при нагреве стального издели под закалку с выдержкой при заданной телшературе 40-60 минут.1. A method for improving the quality of diffusion chrome-plated austenitic steel, about t and h and s, and with the fact that, in order to increase its erosion resistance without reducing the strength of the base metal, the chrome-plated layer is subjected to nitriding when the steel product is heated for quenching with aging with a given telescore 40-60 minutes.
2.Способ выполнени ио и. 1. о т ,1 и ч а ю и; и и с тем, что взамен азотировани хромированного сло примен ют карбоазотированио.2. The method of performing io and. 1. о т, 1 и ч а ю and; and so that carbonization is used instead of nitriding the chrome-plated layer.
