为研究缸套、活塞和活塞环用铸铁的显微组织对耐磨性和抗咬合性的影响,特在一台往复运动摩擦试验机上,以100大型内燃机车柴油机缸套对它们的相互作用关系进行了模拟试验。该试验机是一个四室试验台,在干摩擦、临界摩擦和充足润滑条件下,当温度不超过300℃时,每分钟能进行30～800个往复行程。采用电子装置记录试样表面 In order to study the influence of the microstructure of cylinder liner, piston and piston ring on the wear resistance and seizure resistance, a reciprocating friction test machine was used to test the interaction of 100 large diesel locomotive diesel engine liner A simulation test was carried out. The test machine is a four-chamber test bench, dry friction, critical friction and adequate lubrication conditions, when the temperature does not exceed 300 ℃, the per minute can be 30 to 800 reciprocating stroke. The surface of the sample is recorded using an electronic device
