更高推重比的需求使得航空发动机工作温度不断提高，进而对发动机运动部件润滑涂层提出了更高的要求：宽温域自润滑-低摩擦、高强高韧-抗磨损、优良界面相容性-强结合力，以保证高可靠运行。本项目基于变色龙概念的选材原则及类汗腺的仿生结构设计，构建由硬质骨架/软质润滑相复合，并包含有序纳米孔道作为润滑相输运路径的宽温域硬质自润滑涂层；结合磁控溅射与倾斜沉积技术自下而上构建多级结构：NbAlN/MgAl2O4界面改性层(增强结合力)、Ag/NbN可控补偿层(润滑相可控供给)和NbAgNB硬质自润滑层(类汗腺结构实现高温强度和自适应润滑)。以各级结构的可控生长为基础，探究类汗腺结构生长的动力学效应和热力学机制；围绕尺度和界面效应，研究各级次涂层的强韧化机理及断裂行为；模拟服役环境，揭示润滑相、摩擦反应产物、类汗腺结构的协同作用及自适应润滑机理，为适用于高推重比发动机运动部件润滑保护涂层的应用提供科学依据。

The higher thrust-to-weight ratios has led to an increase in the operating temperature for aero-engines, and cause the higher performance for anti-friction and wear-resistant coatings for engine moving parts: self-lubrication at wide temperature range - low friction, high strength and high toughness – excellent wear resistance, outstanding compatible interface - strong adhesion, which can ensure high reliability for the engine. Based on the chameleon concept and the sudoriferous structure, we will construct a self-lubricating protective coating at wide-temperature, which composed of a hard skeleton/soft lubricated phase and contained ordered nanopores as lubricating phase transport path; We will deposit the NbAlN/MgAl2O4 interface modification layer (enhanced adhesion), Ag/NbN controllable supplying layer (supply lubricating phase) and NbAgNB self-lubricating layer (sudoriferous structure for high-temperature strength and continuous lubrication) from bottom to top by magnetron sputtering and glancing angle deposition. Based on the controllable growth of each structure, the dynamics and thermodynamic mechanism of the growth of sudoriferous structure will be explored. The scale effect and interface effect on the toughening mechanism and fracture behavior will be revealed. The high temperature tribo-test will be appointed to reveal the synergistic effect of lubrication phase, friction products and the sudoriferous structure. The goal of the proposal is to obtain the continuous lubrication hard coating to protect the moving component in the aero-engine with high thrust-weight ratio, and to know how to design and apply the novel hierarchy structure coating in the future.
