Изобретение относитс к способам обработки изделии из сталей, легированных кароидоооразующими элементами, например из стали 1 адфильда, работающих в а&разивной среде.The invention relates to methods for treating an article from steels doped with caroidoorazuyuschimi elements, for example from steel 1 Adfield, working in a and ample environment.
известен способ обработки изделий из сталей , легированных кароидообразующими элементами , например из стали I адфильда, раоотающих в аоразивнои среде, включающий закалку издели в воде и упрочнение поверхностною сло путем наплавки износостойких материалов. Однако он не обеспечивает прочного соединени наплавки с изделием, что приводит к скалыванию поверхностного сло при работе издели ; стоимость изготовлени изделий по известному способу высока .There is a known method for treating products from steels alloyed with karooidoobrazuyuschimi elements, for example, from steel I Adfield, eroding in an aarative environment, including the quenching of the product in water and hardening the surface layer by surfacing wear-resistant materials. However, it does not provide a strong bond between the weld deposition and the product, which leads to spalling of the surface layer during the operation of the product; The cost of manufacturing products according to the known method is high.
Цель изобретени - предотвращение скалывани поверхностного сло изделий, работающих в абразивной среде, и снижение стоимости их изготовлени . Это достигаетс тем, что упрочнение производ т путем проплавлени поверхностного сло наплавл ющимс , например угольным, электродом с последующим охлаждением на воздухе.The purpose of the invention is to prevent the flaking of the surface layer of products operating in an abrasive environment, and reducing the cost of their manufacture. This is achieved by strengthening the surface by melting a surface layer with a filler, for example a carbon, electrode, followed by air cooling.
Способ включает проплавку поверхностного сло неплав щимс электродом (при толщине издели 40 мм толщина проплавленного сло составл ет 4 мм) и охлаждение с умеренной скоростью, например, на воздухе. В результате поверхностный слой издели , например из стали 113Л, приобретает износостойкую ледебуритно-карбидную структуру с твердостью 440-бЬОНв, промежуточный слой -The method involves melting the surface layer with a non-melting electrode (with a product thickness of 40 mm, the thickness of the melted layer is 4 mm) and cooling at a moderate speed, for example, in air. As a result, the surface layer of the product, for example, of steel 113L, acquires a wear-resistant ledeburit-carbide structure with a hardness of 440-BONV, the intermediate layer is
аустенитную структуру с выделени ми карбидов по границам зерен, имеющую твердость 250-320 Нв, а структура сердцевины издели остаетс в зкой - аустенигной. Описываемый способ был проверен на билах из стали Г13Л (проплавление наружного сло толщиной 3-5 мм) при размоле кокса на модели молотковой мельницы. Установлено , что износостойкость бил, изготовленных по описываемому способу, выше вan austenitic structure with carbide precipitates along the grain boundaries, having a hardness of 250-320 Hb, and the core structure of the product remains viscous - austenigous. The described method was tested on G13L steel bilings (penetration of the outer layer 3-5 mm thick) while grinding the coke on a hammer mill model. It is established that the wear resistance of the beams manufactured by the described method is higher in
