发布时间：2018-11-17 06:31
【摘要】：以摩擦因数和摩擦失重量为指标,并参照磨损形貌,研究了载荷对表面镀有Ni-W-SiC镀层的汽车发动机活塞环的摩擦性能的影响。结果表明:随着载荷的增大,摩擦因数降低,而摩擦失重量升高。当载荷为5N时,稳定时摩擦因数约为0.43,摩擦失重量约为1.83 mg;当载荷增至10N和20N时,稳定时摩擦因数分别为0.37和0.32,摩擦失重量分别为2.14mg和2.37mg。载荷变化未影响活塞环表面Ni-W-SiC镀层的摩擦机制。
[Abstract]:The effect of load on the friction performance of the piston ring of automobile engine coated with Ni-W-SiC coating was studied by taking friction coefficient and weight loss as the index and referring to the wear morphology. The results show that the friction coefficient decreases and the friction weight increases with the increase of load. When the load is 5 N, the friction coefficient is about 0.43 and the friction loss weight is about 1.83 mg;. When the load is increased to 10 N and 20 N, the friction coefficient is 0.37 and 0.32, and the friction loss weight is 2.14mg and 2.37 mg respectively. The friction mechanism of Ni-W-SiC coating on piston ring surface was not affected by load change.
