摘要
对蠕墨铸铁膏剂法硼铬共渗的工艺和性能研究表明，该法可显著提高材料表面硬度和耐磨性，同时使抗氧化性和热硬性有较大的提高。
This paper deals with the study on the proccess and properties ofboron－chromizing by pasty agent of cast iron with worm graphite. The experimental workdenots that the quite good technology of boron－chromizing with pasty agent is at 940 ℃hoding 4～5hours. After processing the surface hardness and wear rasistance are notablyraised， mearwhile the oxidation resistance and hot hardnase are considerably raised.
