摘  要:先进表面涂层防护技术是海工装备关键金属运动系统磨损与腐蚀防护、保障海工装备高性能长寿命可靠服役的关键途径。其中,物理气相沉积(PVD)抗磨蚀防护涂层材料兼具耐老化、耐磨性、耐腐蚀等优势,特别是可满足深海或远海机械系统相关精密运动部件的高可靠性与稳定性要求,是抗磨蚀防护的有效技术手段之一。围绕海洋环境PVD抗磨蚀防护涂层材料及应用技术发展现状,重点介绍现有防护涂层材料体系,碳基、氮基涂层因优异耐磨及耐腐蚀性能而获得较多关注,改善膜基界面结合强度及涂层致密性等是提升其抗磨蚀性能的关键因素,而高熵涂层及过渡金属二硫属化物(TMD)涂层磨蚀防护性能也成为基础及应用研究的热点。总结主要的涂层磨蚀评价方法,目前在外加电位下开展涂层磨蚀测试性能评价的应用较多,引入理论计算研究涂层磨蚀性能及相关失效机理已逐渐开展。围绕疲劳/重载下磨蚀防护需求,介绍PVD复合喷涂、微弧氧化、热处理等兼具高承载、长寿命的复合强化抗磨蚀防护涂层材料技术的新进展。列举PVD抗磨蚀涂层在海水传动液压马达和液压泵、船舶低速柴油机柱塞、水下安全阀、钻井泵阀体阀座以及涉海直升机操纵杆等核心涉海装备部件上的典型应用,并对海洋环境PVD抗磨蚀防护涂层的未来发展方向进行思考与展望,为进一步发展高性能海洋抗磨蚀涂层材料技术提供参考。Tribocorrosion is a material-degradation phenomenon resulting from interactive effects between wear and corrosion.For various marine equipment,their key metal motion systems are typically affected by the combined effect of mechanical wear and chemical corrosion under the harsh marine environment,which can directly limit their stability and safety.Thus,comprehensive investigations into tribocorrosion behavior is critical for the design of appropriate engineering materials under the marine environment.Advancing marine exploration and deep-sea development necessitates surface and coating techniques to ensure favorable anti-corrosion and anti-wear performances for moving mechanical components.Many conventional techniques have been used to prepare protective coatings,such as spraying,high-energy beam surface modification,and physical vapor deposition(PVD).Among the diverse developed protective coatings,those realized via PVD exhibit favorable properties,including high corrosion resistance and excellent mechanical performance,which can effectively protect precision moving components used in deep-sea or offshore mechanical systems;thus,they are one of the most effective strategies in this field.This article focuses primarily on the development of anti-tribocorrosion coatings achieved via PVD and technologies used in the marine environment,in addition to the main scientific and technical issues encountered in the field.First,the tribocorrosion performance of carbon-based,nitride-based,high-entropy alloy,and transition metal dichalcogenide coatings are introduced,and the role of components and multilayer/nano-multilayer/nanocomposite/gradient structures on their tribocorrosion performance and related failure mechanism are summarized.The multilayer interface in coatings achieved via PVD not only significantly improves their hardness by hindering dislocation movement but also improves their corrosion resistance by hindering the diffusion of H_(2)O,O_(2),Cl^(-),and Na+corrosives.To evaluate the tribocorrosion performance of
