离子液体/织构化类金刚石碳复合润滑薄膜的构筑及其摩擦学性能的研究

Fabrication and Tribological Study of Ionic Liquid/Texturing Diamond-like Carbon Composite Lubrication Films

  • 摘要: 分别采用激光织构、磁控溅射和浸渍-提拉技术在单晶硅片表面成功构筑了具有离子液体纳米薄膜的织构化类金刚石碳复合润滑薄膜,采用三维轮廓仪和SEM观察了织构化类金刚石碳表面,通过X射线光电子能谱证实了织构化类金刚石碳膜表面离子液体纳米薄膜的存在,并利用微摩擦试验机重点考察和理论分析了这种复合润滑薄膜在较大和微载荷下的摩擦学性能.研究结果表明:这种离子液体/织构化类金刚石碳复合润滑薄膜在微载荷下能够有效地缩短磨合时间、降低摩擦系数,然而其在小载荷下摩擦学性能欠佳.

     

    Abstract: Ionic liquid/texturing diamond-like carbon composite lubrication films were successfully prepared on silicon substrates by a composite technology combining of laser texturing, magnetron sputtering and dip-coating. Textured diamond-like carbon surface were analyzed using non-contact interferometric microscope and scanning electron microscope. Presence of ionic liquid nano-film on textured diamond-like carbon surface was confirmed by using X-ray photoelectron spectrometer, and the tribological properties of the as-prepared composite lubrication films were mainly studied and analyzed theoretically under different applied loads by a micro-tester. The investigation reveals that ionic liquid/textured diamond-like carbon composite lubrication films could shorten running-in time and decrease friction coefficient under low loads, but possess poor tribological behaviors under high loads.
