【 摘 要 】
The effect of rotational speed on the friction and wear properties of 35CrMo/GCr15 was studied under the condition of boundary lubrication. The speed was set as 400r/min,800 r/min,1200r/min,1600r/min,and the load were 200N. Working time was 120min.The ring block friction and wear testing machine were used for testing. The surface morphology changes of wear specimen were analyzed by scanning electron microscope (SEM). The results showed that the main form of the wear of the material was different with speed different. When the rotating speed was low, the wear was mainly abrasive wear, and the wear was mainly adhesive wear at high speed. When the speed was 800r/min, the wear rate was minimum, and the friction coefficient also was minimum. It shows that when the load was constant, the speed was too high or too low, would make the wear and tear intensified.【 预 览 】
