Abstract
To decrease the volatilization rate of Cr on AISI 441 interconnect for Solid Oxide Cells (SOC) application, Mn0.5Co0.5O coatings were deposited using Reactive High Power Impulse Magnetron Sputtering (R-HiPIMS). Three different coating morphologies and preferential growth orientations were obtained by varying bias and temperature settings. All synthetized Mn0.5Co0.5O coatings reduced the volatilization rate of Cr during exposure in dry air at 800 °C for 2000 h. Moreover, the Cr retention power was influenced by the preferential growth orientation of the coating. This study suggests that the deposition parameters of R-HiPIMS can be adjusted to optimize the crystalline orientation and enhance the effectiveness of MnCo oxide coatings as barriers against chromium volatilization.
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.
