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 hardness tester and nanoindentor. https://www.allfixelectricales.shop/product-category/dishwasher-drain-hose/
