Abstract:Transmission electron microscopy (TEM) investigations of the structure and phase composition of ferritic-pearlitic wheel steel mark two surface after electrolyte-plasma surface hardening are presented. Initially the morphology of the steel matrix consists of lamellar perlite and non-fragmented and fragmented ferrite. Electrolytic plasma quenching of the steel surface results in the martensite transformation, steel self-tempering, and the formation of cementite particles in all martensite crystals.
