| 摘 要： | 采用盘-销式摩擦试验机,以司班-80/二聚酸体系作润滑油添加剂,在陶瓷-陶瓷(A l2O3-A l2O3)表面进行摩擦磨损实验。采用差示扫描量热法(DSC)探讨了单体在陶瓷表面的吸附类型;采用扫描电子显微镜(SEM)、X射线光电子能谱仪(XPS)、傅立叶红外光谱仪(IR)对盘上磨痕进行表面分析。结果表明添加剂在磨痕处生成了保护性体型聚酯膜。其摩擦聚合机制为:在摩擦过程中,二聚酸以物理吸附的方式吸附在陶瓷表面;由于二聚酸的羧基与司班-80的羟基发生摩擦聚合反应,在陶瓷表面生成体型聚酯膜,从而降低陶瓷表面的磨损。

| Abstract: | The tribological tests were carried out in a pin-on-disk tester by using span-80/dimer acid as the lubricant additives to lubricate the surface of ceramic-on-ceramic under boundary lubricant condition.The monomer absorption was studied by differential scanning calorimetry(DSC).The surface of the wear scar was analyzed by scanning electron microscopy(SEM),X-ray photoelectron spectroscopy(XPS) and fourier infrared spectroscopy(IR).The result indicate that the additives can generate protective polyester on the surface of alumina.A mechanism of reducing wear on ceramic-on-ceramic interface can be deduced:firstly,the dimer acid was absorbed physically on the surface of the ceramic;secondly,a crosslinked film of polyester was generated on the surface of ceramic by the tribopolymerization of carboxyl group of dimmer acid with hydroxy group of span-80;as a result,the polyester film obtained reduced wear of the surface of ceramic. |
