Description
Изобретение относитс к изысканию износостойких чугунов, предназначенных дл изготовлени изделий, работающих в услови х гидроабразивного износа и ударных нагрузок, например запасных частей дробеметных аппаратов .The invention relates to the search for wear-resistant cast irons for the manufacture of products operating under conditions of hydro-abrasive wear and impact loads, for example, spare parts for shot-blasting apparatuses.
Известен износостойкий чугун, содержащий углерод, кремний, марганец, хром, никель и железо (например чугун ИЧХ2Г4). Однако такой чугун не обеспечивает достаточной стойкости против абразивного износа и имеет склонность к образованию гор чих трещин.Known wear-resistant cast iron containing carbon, silicon, manganese, chromium, nickel and iron (for example, IChH2G4 cast iron). However, such cast iron does not provide sufficient resistance to abrasive wear and has a tendency to the formation of hot cracks.
Предлагаемый износостойкий чугун отличаетс повышенным содержанием хрома, пониженным содержанием никел и введением в его состав цери . Это позвол ет повысить износостойкость и механические свойства (ударную в зкость, твердость).The proposed wear-resistant cast iron is characterized by a high chromium content, low nickel content and the introduction of cerium into its composition. This makes it possible to increase wear resistance and mechanical properties (impact strength, hardness).
Химический состав чугуна следующий (в %):The chemical composition of cast iron is as follows (in%):
