活塞环最好的组织是细的珠光体,带细纲状磷化物共晶体,及大量较小的涡流肤(B型)石墨.这种组织保证了活塞环所需的一切特性;由于珠光体和有利的石墨形状而得到高的强度;由于石墨析出的细鳞而具有大的弹性系数;由于良好的石墨形状及无铁素体而不易产生塑性变形;致密的珠光体基体及网状磷化物共晶体和大量片状石墨保证了铸铁的耐磨性.本文将讨论获得这一优质活塞环的控制方法.
The best organization of piston rings is fine pearlite with fine-mesh phosphide cocrystal and a large number of smaller eddy-current skin (type B) graphite, which ensures all the necessary features of the piston ring; as pearlite And favorable graphite shape to obtain high strength; due to graphite fine scale precipitation has a large elastic modulus; because of good graphite shape and non-ferrite is not easy to produce plastic deformation; dense pearlite matrix and reticular phosphide Co-crystals and a large amount of flake graphite guarantee the wear resistance of cast iron.This article will discuss the control method to obtain this high quality piston ring.
