Material dependent surface and subsurface properties of hybrid components

Abstract Tailored forming is used to produce hybrid components in which the materials are locally adapted different types of physical, chemical and tribological requirements. In this paper, a Forming process chain for production shaft with bearing seat investigated. The consists manufacturing steps laser hot-wire cladding, cross-wedge rolling, turning deep rolling. A cylindrical bar made mild steel C22.8 as base material, cladding martensitic valve X45CrSi9-3 applied area achieve strength hardness required. It investigated how surface subsurface properties component, such hardness, microstructure residual stress state, change within chain. results compared previous study austenitic stainless X2CrNiMo19-12 was material. shown that state after hot depends on thermal expansion coefficients
