前言柴油机汽缸套在经过不同的使用时间以后就会损坏,其主要标志是磨损,这种磨损的一般特征是活塞坏与汽缸套之间的间隙扩大,造成工作时漏气,从而使发动机的效率降低,产生噪音、燃料消耗量增加。因此提高汽缸套的寿命,不仅提高内燃机的工作效率,而且延长内燃机的工作时间。从二十年代开始,人们就对铸铁汽缸套的耐磨性和铸铁的金相组织及化学成分之间的关系进行了系统的研究。从珠光体铸铁进而到应用高磷铸铁。近十几年米国外采用在铸铁中加 Foreword Diesel cylinder liner will damage after different use time, the main symbol is wear and tear, the general characteristics of this wear is the gap between piston bad and cylinder liner to expand, resulting in leakage of work, so that the efficiency of the engine Reduce, produce noise, increase fuel consumption. Therefore, the life of the cylinder liner is increased, which not only improves the working efficiency of the internal combustion engine but also lengthens the working time of the internal combustion engine. From the beginning of the twenties, people conducted a systematic study on the relationship between the wear resistance of cast iron cylinder liner and the microstructure and chemical composition of cast iron. From pearlite cast iron to high phosphorus cast iron. Nearly a decade abroad used in cast iron in Canada
