Abstract

High infrared emissivity coatings have important engineering value in aerospace and electronic devices. In this study, a new method for preparing high infrared emissivity coatings using magnetic field-assisted jet electrodeposition was prepared. The magnetic field-assisted jet electrodeposition technique can be used to prepare coatings with rough structures, and the infrared emissivity of nickel particle coatings can reach 0.80 at a magnetic field intensity of 100 mT, which is significantly improved compared with the nickel coatings (0.155) prepared by conventional electrodeposition. A nickel-based SiC composite coating with high infrared emissivity was prepared by combining magnetic field-assisted jet electrodeposition with SiC particles. Compared with the nickel particle coating, the infrared emissivity of the nickel-based SiC composite coating is further improved. At a concentration of 6 g/L SiC particles, the infrared emissivity of the nickel-based SiC composite coating reached 0.94. The synergistic effect of magnetic field-assisted jet electrodeposition and SiC particles can realize the nickel coatings into coatings with high infrared emissivity.

利用磁场辅助射流电沉积技术制备具有增强红外发射率的高性能Ni-SiC复合涂层

高红外发射率涂料在航空航天和电子器件中具有重要的工程价值。本文研究了一种利用磁场辅助射流电沉积制备高红外发射率涂层的新方法。利用磁场辅助射流电沉积技术可以制备出结构粗糙的镀层，在100 mT磁场强度下，镍颗粒镀层的红外发射率可达0.80，与常规电沉积镍镀层（0.155）相比有显著提高。采用磁场辅助喷射电沉积方法，制备了具有高红外发射率的镍基SiC复合涂层。与镍颗粒涂层相比，镍基SiC复合涂层的红外发射率进一步提高。当SiC颗粒浓度为6 g/L时，镍基SiC复合涂层的红外发射率达到0.94。磁场辅助射流电沉积与碳化硅颗粒的协同作用可使镍镀层成为具有高红外发射率的镀层。

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.
