High-temperature oxidation resistances of coatings on Inconel 718 alloy by boriding, aluminizing, and boroaluminizing
Inconel 718 alloy is used at high temperatures and is prone to react with oxygen, leading to a decrease in its high-temperature performance. To improve the high-temperature oxidation resistance of Inconel 718 alloy, in this work, three coatings on Inconel 718 alloy were manufactured by boriding, aluminizing, and boroaluminizing, and the high-temperature oxidation resistances at 800 °C, 900 °C and 1000 °C were investigated. The results showed that the maximum thickness of coatings can be achieved >200 μm. Moreover, these three coatings can improve the high-temperature oxidation resistance of Inconel 718 alloy, and the boroaluminized coating has the best high-temperature oxidation resistance. Besides, the reason for the improvement of high-temperature oxidation resistance is due to the formation of dense oxide layers during the oxidation process, which can prevent further oxidation.
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.
