Zr3O-ZrC/graphene strengthened layer directly prepared on the surface of metal Zr by plasma heat treatment
Zr3O-ZrC/graphene composite layer was directly in-situ grown on the surface of Zr foil by plasma heat treatment method.The microstructure and component of the as-prepared sample were systematically characterized by X-ray diffraction (XRD), Raman spectrum and scanning electron microscopy (SEM).The surface hardness was both characterized by micro har
