摘要：

The paper presents studies on corrosion resistance of chromium cast steels with additions of Ni and Mo after chemical and heat treatment operations. The chromium content varied from 6 to 18 weight %. Corrosion tests were performed according to modified methodology of ASTM test and results of presented in position [17]. The range of investigations included the corrosion studies of samples after heat treatment operations (hardening and tempering) and after carburising with consecutive hardening. Analyses have shown the influence of those operations on corrosion resistance of studied alloys. The carburising process caused the structural changes in surface layer of cast steel, increasing the operation properties. Obtained results were compared with observation of low-alloyed steel samples after heat treatment.
