Description
Summary:[Display omitted] ► Diffusion barrier to oxygen were manufactured by pack cementation diffusion process. ► The use of CrSi2+Si and TiSi2+Si as masteralloys increased the quality of the coating. ► Thermodynamic stability (coatings/vanadium) was obtained at the operating temperature. ► MSi2 coatings developed low growing oxide scale in air and at low oxygen pressure. ► Coatings presented high compatibility with liquid sodium (
