Abstract: In this paper the results of thermal simulation of formation composite layer on model cast steel casting process have been presented. The objective of this research was to determine the technological parameters of the formation composite layer process which enables obtaining good quality reinforcement layer of the desirable thickness. For assumed changes of chosen technological parameters, distribution of temperature in model casting as well as course of temperature changes in characteristic point of composite insert have been determined. Simulations have been carried out for two different materials of compositing element (insert) and three different pouring temperatures with software NovaFlow&Solid 2.9 r81. Obtaining good quality composite layer with desirable thickness depends on parameters of the process and level of heating during the casting process. The researches enable determination of the technological parameters that directly influence on this process and the criterions to be met by the casting technology of this kind. The results obtained and their experimental verification will make it possible to form a basis for working out the guidelines and principles for the design technology of casting with composite layer on chosen surfaces productions.
