    摘要:

    采用表面化学改性的方法得到硬脂酸修饰的纳米碳球,在四球摩擦试验机上考察纳米碳球在合成酯类润滑油中的抗摩擦性能,探讨纳米碳球的抗磨与润滑机制。结果表明,通过表面改性,显著提高纳米碳球在润滑油中的分散稳定性;纳米碳球作为合成酯润滑油抗磨剂表现出优良的抗磨减摩性能;在转速1.200 r/min,载荷150 N的实验条件下,质量分数0.07%的改性纳米碳球可使三羟甲基丙烷混酸酯平均摩擦因数减小幅度达到30%左右,磨损率降低33%,质量分数0.15%的改性纳米碳球可使季戊四醇油酸酯的平均摩擦因数降低幅度达到50%以上,磨损率降低14.6%

    Abstract:

    The stearic acid-modified nanocarbon spheres were prepared through surface chemical modification method.The tribology behavior of nanocarbon spheres as anti-wear additive in synthetic ester lubricating oil was investigated using four ball testing machine of friction and wear,and the friction reducing and anti-wear mechanism was discussed.The results show that the dispersion stability of nanocarbon spheres in synthetic ester lubricating oil is significantly improved through surface chemical modification,and nanocarbon spheres as a synthetic ester lubricating oil additive exhibit excellent antiwear and friction reducing behavior.At the experimental conditions of rotation rate of 1 200 r/min and load of 150 N,nanocarbon spheres with weigh percentage as low as 0.07% as additive in trimethylolpropane ester can decrease the friction coefficient by 30%,and the wear rate by 33%,and nanocarbon spheres with weigh percentage as low as 0.15% as additive in pentaerythritol oleic acid ester can decrease the friction coefficient by above 50%,and the wear rate by 14.6%.
