摘 要： Friction, wear, and vibration behaviors of oil-and grease-lubricated laser textured point contacts formed between AISI 52100 steel surfaces have been experimentally investigated under the unidirectional sliding motion using a ball-on-disk configuration. The performance behaviors of lubricated concentrated contacts formed between the lapped disk/lapped ball and textured disk/lapped ball have been compared at two Hertzian pressures (0.4 GPa and 0.7 GPa) and two sliding speeds (0.8 m/s and 2.4 m/s) using lubricating oil and grease. For the geometric configuration of point contacts adopted in the investigations, the textured point contacts lubricated with grease yielded reductions in the friction coefficient and specific wear rate (SWR) of the balls as compared to the oil-lubricated textured contacts. Moreover, reduction in the amplitudes of vibrations (at normal contact resonance frequencies) has also been observed with the grease-lubricated textured point contacts in comparison to the corresponding oil-lubricated cases.

采用球-盘结构，在单向滑动运动条件下，对AISI 52100钢表面之间形成的油润滑和油脂润滑的激光纹理点接触的摩擦、磨损和振动行为进行了实验研究。在两种赫兹压力（0.4 GPa 和 0.7 GPa）和两种滑动速度（0.8 m/s 和 2.4 m/s）下，比较了经过研磨盘/研磨球与纹理盘/研磨球之间形成的润滑集中接触点的性能表现，使用润滑油和润滑脂进行测试。对于本研究中采用的点接触几何配置，发现与油润滑的纹理接触相比，油脂润滑的纹理点接触可降低球体的摩擦系数和比磨损率（SWR）。此外，与相应的油润滑情况相比，油脂润滑的纹理点接触在正常接触共振频率下的振动振幅也有所减小。
