Résumé

Important changes in the ratio of constitutive phases take place during heating of galvanized parts due to Zn coating layer changed into Zn-Fe alloy. The work deals with a mathematical correlation between diffusion phenomena occurring in layer, depending on temperature and time of heat treatment, and iron content of coating. Both terms define a certain structure.
