Zusammenfassung:Different modes of complex magnetic-abrasive and chemical/thermal surface treatment for VT9 alloy specimens are discussed. Based on the obtained results of X-ray diffraction, microstructural and durametric analyzes, the appropriate characteristics of the specimen test portion surface layer are obtained. The conducted fatigue tests of VT9 alloy specimens with and without the above complex treatment revealed that the endurance limit of the former ones exceeds that of the latter by 40%.
