Temperature curve, microstructure evolution, and interface bonding of plasma sprayed nickel-based coating under plasma arc/high-frequency induction remelting
An 800 μm thick NiCrBSi coating was applied to the surface of a cylindrical substrate using plasma spraying and subsequently remelted via plasma arc and induction heating processes. This work investigated the temperature variations and the influence of the skin effect during the induction remelting process. Additionally, a comprehensive analysis was conducted on the microstructure and interface bonding of the coating upon two-step remelting. Results demonstrate that during induction remelting, the temperature curve tends to stabilize when the coating temperature exceeds 900 °C and reaches its peak value. The effective depth of induction heating is approximately 250 μm. The bonding between the coating and the substrate transitions from mechanical to metallurgical bonding, forming a distinct diffusion layer comprising nickel and iron at the interface. The remelting effect is affected by the thickness of the coating. Furthermore, reducing pores at the coating interface through two-step remelting enhances the bonding strength. Consequently, two-step remelting is an effective method for improving the microstructure and interface bonding of coatings.
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.
