The main purpose of the present study is to verify the possibility of decarbonizing the surface of heat-resistant ductile iron GJS-XSiMo5-1 to provide a significant difference in carbon content between this material and gray cast iron EN-GJL-250. In the future, this will allow to increase the diffusion of elements during the creation of the two-layered material using the casting process with materials in a liquid state and solid state. The above method was assumed to solve the problem of defects on turbocharger’s housing in an economically justified manner which occurred in some high-performance premium applications. Evaluation of decarbonized surface quality was investigated by microstructure observation (light microscopy) and alloy elements diffusion (scanning electron microscopy), and hardness measurement and the element content were checked by spark optical emission spectrometry and glow discharge optical emission spectrometry, respectively.
