Abstract
Oxidation behavior of the NiCrAlY coatings with/without man-made interdiffusion (M-IDZ) layers at 1050 °C is investigated. Results indicate that four kinds of the M-IDZs are designed, which are based on the chemical composition of the IDZ, and can be applied between the single crystal superalloy and the NiCrAlY coating. Their additions do not affect the formation and thickening of the α-Al2O3 scales, and show excellent oxidation resistance. After oxidation, the thicknesses of the changed superalloys beneath the coatings with M-IDZs are much less than the case of the NiCrAlY coating without M-IDZs, weakening the side effects of the element interdiffusion on the superalloy. At the same time, the existence of the M-IDZs can accelerate the transformation from needle-like σ and μ phases to P phase.
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.
