摘　　要：Dense zirconium coatings on copper substrates were obtained in an alumina crucible and a stainless steel crucible from FLiNaK-K_(2)ZrF_(6)molten salt at 1023 K.Due to the potential difierences between copper and zirconium,zirconium can difiuse into the copper substrate to form zirconium alloys on the surface of copper substrates in the course of deposition.The coating deposited in a stainless steel crucible has a gray surface.The components of the coating are mainly CuZr2alloy and Cu_(10)Zr_(7)alloy,and,the outermost layer of the coating is a layer of amorphous pure zirconium.The coating deposited in an alumina crucible has a silvery white metallic luster.The components of the coating are mainly Cu-Zr-Al intermetallic compounds,AlCu_(2)Zr,ZrAl,AlCu and CuZr.Furthermore,two types of zirconium coatings can greatly increase the hardness of the substrate.
