Abstract

A self-lubricating AAO-Cu/Ni-P composite coating was deposited on the surface of 6061 aluminum alloy. An anodized intermediate layer (AAO) was introduced to enhance the adhesion and wear resistance of the coating. The microstructure, element distribution, and properties of the composite coating were comprehensively analyzed and contrasted with those of the traditional Ni-P coating pretreated by zinc immersion and the AAO/Ni-P coating. The outcomes indicated that the bonding strength of both the AAO/Ni-P and AAO-Cu/Ni-P coatings was notably improved compared to the traditional Ni-P coating. Unlike the AAO/Ni-P coating, the AAO-Cu/Ni-P coating displayed a significant enhancement in friction resistance due to its self-lubricating properties. Consequently, the friction coefficient was reduced by approximately 42.9 % and the volume wear decreased by 86.7 %. This research provides valuable insights into the friction and wear mechanisms of AAO-Cu/Ni-P composite coatings, offering technical support for the development of high-performance aluminum alloys.

一种6061铝合金表面具有中间阳极氧化层的自润滑复合涂层

在6061铝合金表面沉积了自润滑的AAO-Cu/Ni-P复合镀层。为了提高涂层的附着力和耐磨性，引入了阳极氧化中间层（AAO）。对复合镀层的显微组织、元素分布和性能进行了综合分析，并与传统浸锌预处理的Ni-P镀层和AAO/Ni-P镀层进行了对比。结果表明，与传统的Ni-P涂层相比，AAO/Ni-P涂层和AAO- cu /Ni-P涂层的结合强度均有显著提高。与AAO/Ni-P涂层不同，AAO- cu /Ni-P涂层由于具有自润滑特性，其摩擦阻力显著增强。因此，摩擦系数降低了约42.9%，体积磨损降低了86.7%。本研究为研究AAO-Cu/Ni-P复合涂层的摩擦磨损机理提供了有价值的见解，为高性能铝合金的开发提供了技术支持。

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.
