Abstract
Cr/CrAl multilayer coatings were prepared on Zr-4 surfaces via magnetron sputtering. The effect of multilayer structure on the microstructure, wettability and steam oxidation resistance of the coatings was investigated. The Cr/CrAl multilayer coatings have BCC structure and hydrophobicity. The steam test at 1000 °C demonstrated that (Cr/CrAl)16 exhibited the excellent resistance to steam oxidation, and Al2O3 formation was observed in the outer layer of the oxide film. The (Cr/CrAl)16 coating has been demonstrated to retard the rate of oxidation of the substrate in a steam environment at 1200 °C. In addition, the oxidation behavior of the Cr/CrAl multilayer coatings was analyzed in detail.
期刊介绍:
Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance:
A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting.
B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
