项目摘要

Light-weight metallic materials, such as Mg, Al and Ti alloys, are known for high strength-to-weight ratio, which makes them attractive to many applications including transportation, energy and biomedical devices. However high chemical reactivity and low wear resistance significantly hinder their use in demanding applications. Plasma electrolytic oxidation (PEO) is an advanced surface treatment developed for light alloys, which has recently attracted interest due to relative simplicity, environmental benefits and high performance of the coatings produced. However conventional PEO coatings can provide only passive protection to light alloys, so they need to be further engineered to enable active and multifunctional performance in line with modern smart materials approaches. Innovative 2D materials, such as MXenes that possess layered structures and diverse properties, can provide a suitable platform for engineering of PEO coatings to address problems pertinent to light alloys. However, there are fundamental problems associated with direct incorporation of these materials into growing PEO coatings, addressing which will require tailoring MXene's chemistry and manufacturing routes as well as exploring alternative surface engineering strategies. This project will be aiming at creating modified MXene type additives and exploring new ways to introduce them into PEO coatings formed on various light alloy substrates. This will be followed by advanced surface characterisation and evaluation to achieve a better understanding of the potential for innovative applications of the new multifunctional PEO coatings.

轻质金属材料，如镁、铝和钛合金，以其高的强度/重量比而闻名，这使得它们在交通、能源和生物医学设备等许多应用领域具有吸引力。然而，高化学反应活性和低耐磨性大大阻碍了它们在要求苛刻的应用中的使用。等离子体电解氧化(PEO)是一种用于轻合金的先进表面处理技术，由于其制备的涂层相对简单、环保和高性能，近年来引起了人们的兴趣。然而，传统的PEO涂层只能为轻合金提供被动保护，因此需要进一步设计，以实现符合现代智能材料方法的主动和多功能性能。创新的2D材料，如具有层状结构和不同性质的MXenes，可以为PEO涂层的工程设计提供一个合适的平台，以解决与轻合金相关的问题。然而，将这些材料直接融入不断增长的PEO涂层中存在一些根本问题，解决这些问题将需要定制MXene的化学和制造路线，以及探索替代的表面工程策略。该项目的目标是创造改性的MXEN型添加剂，并探索将其引入在各种轻合金基材上形成的PEO涂层中的新方法。随后将进行先进的表面表征和评估，以更好地了解新型多功能聚氧化乙烯涂料的创新应用潜力。
