离子液体作为Si3N4-Ti3SiC2摩擦副润滑剂的摩擦学性能研究

Tribological Behavior of Si3N4-Ti3SiC2 Contacts Lubricated by Ionic Liquids

  • 摘要: 采用SRV摩擦磨损试验机在室温及100 ℃下考察了两种离子液体(L-B106 和L-P106)、丙三醇、水作为Si3N4-Ti3SiC2摩擦副润滑剂的摩擦学行为,利用扫描电子显微镜(SEM)及X光电子能谱(XPS)对磨损表面进行了分析.结果表明:室温、20 N条件下,两种离子液体和丙三醇抗磨和减摩性能相当,室温、100 ℃条件下,L-P106相较于L-B106具有更好的润滑性能,且其抗磨和减摩性能均优于丙三醇,作为Si3N4-Ti3SiC2摩擦副润滑剂具有在苛刻环境条件下使用的应用前景. XPS分析结果表明:Ti3SiC2材料在摩擦过程中在摩擦热作用下生成了SiOx、TiO2,进而有效提高了Ti3SiC2摩擦副材料的抗磨损性能;此外,离子液体中的活性元素在Si3N4-Ti3SiC2摩擦副表面发生了复杂的摩擦化学反应,生成了由氟化钛、磷酸钛及硼酸钛等组成的具有减摩和抗磨性能的边界润滑膜.

     

    Abstract: The tribological behavior of Si3N4-Ti3SiC2 contacts lubricated by ionic liquids (ILs), L-B106 and L-P106, were investigated on an Optimol SRV oscillating reciprocating friction and wear tester. As the results, L-P106 and L-B106 showed good tribological behavior comparable to Glycerol under a load of 20 N at room temperature. L-P106 showed the best antiwear and friction-reduction ability under the load of 100 N at both 25 ℃ and 100 ℃. The elemental composition and chemical nature of the boundary films generated on worn Ti3SiC2 surface were analyzed on a scanning electron microscope with a Kevex energy dispersive X-ray analyzer attachment and X-ray photoelectron spectrometer. It indicates that tribochemical reactions of the ILs with Ti3SiC2 surface occurred during the sliding process. TiO2, SiOx and complicated Ti-containing compound likely TiF4 and Ti(BO2)4 or Ti3(PO)4 boundary film were formed on the worn Ti3SiC2 surface, which enhanced the antiwear and friction-reduction ability of the Ti3SiC2 surface.
