AbstractVanadium carbide (VC) coatings were prepared on 3Cr13 stainless steel using FLiNaK salts through thermal diffusion carbide coating process (TD) for different time. The morphology, composition, hardness and growth kinetics of the VC coatings were investigated by scanning electron microscope (SEM), X-ray diffractometer (XRD), Vickers indenter, electronic probe microanalysis (EPMA) and energy dispersive X-ray spectrometry (EDX). Results show that the VC coatings of 3-5 mu m in thickness form on the surface of 3Cr13 stainless steel. The coatings are petal-shaped and contain traces of Si and Fe. The average hardness of the VC coating is up to 32220 MPa and there is a parabola relationship between the thickness of the coatings and the treatment time. VC coatings are covered by rimous SiO2 phases with the thickness of hundreds of nanometers. The cracks of SiO2 phases result from the tensile stress during the cooling process, which derive from the different thermal expansivity between VC coating and SiO2 phase. The present study also indicates the potential application of FLiNaK salts in TD process.
