Metal Science and Heat Treatment Aims and scope

Abstract

The structure and properties of surface layers on low-carbon martensitic steel 12Kh2G2NMFT after low-temperature sulfonitrocarburizing in ecologically safe salt solutions based on sodium cyanate are studied. The phase composition and the distribution of elements and of the hardness over the thickness of diffusion layers are determined. The effect of the sizes of characteristic structural components on the morphology of the carbonitride phase of the diffusion layer and on the activation energy is investigated.
