Abstract

Aluminum and aluminum alloys are widely used in aerospace, automobile manufacturing, electronic equipment, and other fields due to their lightweight and excellent performance. Micro-arc oxidation (MAO) technology improves the properties of aluminum by creating a hard ceramic film on its surface. However, traditional MAO is inconvenient for handling large workpieces, which has promoted the development of scanning micro-arc oxidation (SMAO). This paper combines laser texture pretreatment with SMAO technology to prepare a composite coating. The results show that this technology can significantly improve coating performance. This paper prepares high wear-resistant and corrosion-resistant coatings by optimizing SMAO process parameters and selecting laser pretreatment methods, which provides a new method for the application of aluminum alloys in high-demand fields.

机械臂辅助激光织构与扫描微弧氧化协同改性铝合金表面性能的研究

铝及铝合金因其重量轻、性能优异而广泛应用于航空航天、汽车制造、电子设备等领域。微弧氧化（MAO）技术通过在铝表面形成坚硬的陶瓷膜来改善铝的性能。然而，传统的微弧氧化技术在处理大型工件时不方便，这促进了扫描微弧氧化技术的发展。本文将激光织构预处理与smo技术相结合，制备复合涂层。结果表明，该工艺能显著提高涂层性能。本文通过优化SMAO工艺参数和选择激光预处理方法制备了高耐磨耐腐蚀涂层，为铝合金在高要求领域的应用提供了新的途径。

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.
