加硼铸铁是制造活塞环和气缸套的一种极好的耐磨材料,国外在四十年代就开始研究,到六十年代用于汽车缸套和活塞环,显示了极大的优越性,并逐步扩大到其它使用领域。国内一些工厂在1972年开始相继进行加硼铸铁的研究,到目前为止已获得了很大成
Boron-added cast iron is an excellent wear-resistant material for piston rings and cylinder liners. Research abroad began in the 1940s and was used in automotive cylinder liners and piston rings in the 1960s to demonstrate great superiority. And gradually expanded to other areas of use. Some factories in China began to carry out boron-added cast iron research in 1972, so far it has gained a great deal
