Sažetak
The chemical composition of steel has the most important role in producing a hard carbide layer by applying a thermo-reactive diffusion coating on the tool surface. A thermo dynamical model of the hard carbide layer formation is presented in this paper. Also, effects of carbon contents and alloying elements on the kinetics of vanadium carbide layer forming have been quantified. Three basic classes of tool steels have been analyzed considering the feasibility of diffusion carbide coating for application. A complex effect of austenitic-carbide microstructure on the process of carbide layer formation has been studied for the cold work tool steel class. The phenomenon of partial decarburization in the hot work tool steel class has been depicted, as well as the application of computer simulation for the preceding carburization as a step to eliminate such a phenomenon. Complex effects of chemical composition and microstructure on the carbide layer formation have been described for the high speed steel class.
