The results show that Re-K-Zn compound modificator has remarkable effects in high Chromium white cast iron when the modificator has 0.5%Re+2.0%K+0.008%Zn. The modificator not only or bar-like carbides but also improved the mechanical properties of high chromium white cast iron,with its impact toughness enhanced from 7.0J/cm2 to 11.7J/cm2 and its hardness enhanced from 54HRC to 57HRC, and the wear resistance increased by 350%.
