将含有一定浓度氮化硅(Si_3N_4)和氮化铝(A1N)纳米陶瓷粒子的分散溶液作为润滑油添加剂(纳米陶瓷粒子质量百分比小于3%),采用四球试验机考察纳米陶瓷添加剂的抗磨和极压性能,确定了纳米陶瓷添加剂在基础油中的最佳浓度;利用 NT 场致发射扫描式电子显微镜、高分辨率扫描电子显微镜,观察磨损表面的纳米粒子,并对其抗磨和极压机理进行了探讨。
The dispersion solution containing a certain concentration of silicon nitride (Si_3N_4) and aluminum nitride (A1N) nano-ceramic particles as a lubricating oil additive (mass percentage of nano-ceramic particles is less than 3%), using a four-ball test machine to examine the anti- The best concentration of nano-ceramic additive in the base oil was determined by the extreme pressure performance. Using NT field emission scanning electron microscope and high resolution scanning electron microscope, the worn surface nanoparticles were observed, and their antiwear and extreme pressure Mechanism is discussed.
