Structural heredity of cast iron in bimetallic products

Abstract

Properties of cast iron on the bimetallic part depend on the initial structural state of the cladded cast iron and technological parameters of its induction cladding process. Methodology of predicting the properties of the cast iron in the bimetallic valve tappets ICE largest hardness billets was used for cladding, the silicon content in the alloy cladding and the technological parameters of the process, as well. A hereditary relationship between the initial state of the cast iron of the semi-finished product, used for induction cladding, and the structural state of the layer of weld on the steel base of the part, has been established.
