| Abstract: | A deep cooling treatment process was introduced into the research on properties of hi -chromium cast iron, and an approach was made to the effects of the deep cooling treatment on the macro-mechanical properties and wear resistance of the material. The test results showed that properly deep cooling treating could increase hardness, anti-impact fatigue strength, as well as sliding and rolling wear resistance of the hi-chromium cast iron, however, such effects were limited. |
