【摘要】：采用绿色水热制备方法,以葡萄糖为前身化合物一步制得直径在400~500 nm、尺寸均匀的单分散微碳球,采用扫描电子显微镜、红外光谱等手段对微碳球的表面形貌及化学特性进行表征,利用多功能摩擦磨损试验机考察了微碳球作为润滑油添加剂在铝合金钢摩擦副的减摩耐磨特性,探讨了微碳球的润滑作用机理。结果表明:将微碳球作为液体石蜡和商用机油润滑添加剂可以显著提高铝合金钢摩擦副上的摩擦学性能,这主要是因为在滑动过程中微碳球可能进入到接触区,阻止摩擦副之间的直接接触,并起到纳米滚珠作用。
[Abstract]:Monodisperse microcarbon spheres with a diameter of 400 ~ 500 nm and uniform size were prepared by green hydrothermal method using glucose as precursor compound. Scanning electron microscopy (SEM) was used. The surface morphology and chemical properties of micro-carbon ball were characterized by infrared spectroscopy. The friction and wear resistance of micro-carbon ball as lubricating oil additive in friction pair of aluminum alloy was investigated by multi-function friction and wear tester. The lubrication mechanism of micro-carbon ball is discussed. The results show that the tribological properties of aluminum alloy steel friction pair can be improved by using micro-carbon ball as liquid paraffin and commercial oil lubricating additive. This is mainly due to the fact that the micro-carbon ball may enter the contact area during the sliding process to prevent the direct contact between the friction pairs and play the role of nanometer ball.
