多元素钒钛球墨铸铁活塞环的研究与应用

Development and Application of Multi-Alloys Containing V-Ti Nodular Iron Piston Rings

介绍了多元素钒钛球墨铸铁活塞环的耐磨损机理,铸造工艺、综合性能、化学成分、金相组织概况及这种活塞环装机试验和台架快磨试验结果。说明多元素钒钛球墨铸铁是一种值得推广应用的新型优质活塞环材料。

The wear-resistance mechanism, foundry method, comprehensive properties, chemical composition, microstructure of the multi-alloys-containing V-Ti nodular iron piston ring was described. The result of engine-running test of the piston ring and the test result of the piston ring put on a self-made quick-wear-off test machine was introduced. It was concluded that the multi-alloys-containing V-Ti nodular iron is a new type of high quality piston ring material which should be popularized and applied.
