摘　　要：具有突出耐润滑油性能的红外与激光兼容涂层广泛应用在各类飞行器多频谱兼容隐身领域,且应用前景广阔,是隐身材料领域的研究热点。本文采用绢云母改性方法,制备得到了一种具有突出耐润滑油性能的复合涂层([PU)/Al-Sm_(2)O_(3)],并系统地研究了涂层的理化性能变化规律。研究结果表明:绢云母改性后的涂层表面微观结构依然十分规整,PU树脂对涂层中颜/填料的包覆依然紧密,微观结构保持稳定。绢云母改性可明显改善涂层的规整度、致密度和片状铝粉的排布状态,促使涂层发射率显著降低,涂层对润滑油腐蚀的稳定性得到显著提高。绢云母改性可明显提高涂层的耐冲击强度,可使涂层在长时间的润滑油腐蚀过程中仍然保持在最优状态。Infrared and laser compatible coating with outstanding lubricating oil resistance has been widely applied in multi-spectral compatible stealth fields for various aircrafts,demonstrating broad application prospects and currently constituting a research hotspot in stealth materials.Using the sericite modification method,a kind of composite coating([PU)/Al-Sm_(2)O_(3)]with outstanding lubricating oil resistance was prepared in this paper,and the changes in the physical and chemical properties of the coating were studied systematically.The research results showed that,the microstructure of the coating surface modified with sericite was still very regular,and the PU resin still tightly wraped the pigment/filler in the coating,maintaining a stable microstructure.Modification of sericite could significantly improve the regularity,density,and arrangement of flake aluminum powder in the coating,leading to a significant decrease in coating emissivity and a significant improvement in the stability of coating against lubricating oil corrosion.Modification of sericite could significantly improve the impact strength of the coating,allowing it to remain in its optimal state even during prolonged lubricating oil corrosion process.
