目前我国绝大多数活塞环材料采用铬、钼、铜、钨、钒、钛等元素的片状右墨合金铸铁。随着动力机械的迅速发展和内燃机的不断强化,对活塞环提出了越来越高的要求。为此,我们和聊城活塞环厂进行了活塞环新材料的研究工作,结果获得了石墨形态介于 At present, most of the piston ring material in our country is made of flaky right-ink alloy cast iron of chromium, molybdenum, copper, tungsten, vanadium, titanium and other elements. With the rapid development of power machinery and the continuous strengthening of internal combustion engines, piston rings are set higher and higher requirements. To this end, we Liaocheng Piston Ring Factory and the piston ring of new materials research work, the results obtained graphite morphology between
