A new type of high chromium cast iron (HCCI) was prepared, and its microstructure, mechanical properties, abrasion resistance were investigated systematically. Results showed that after surface carburizing chromizing, the microstructure HCCI mainly consists martensite, boride (M2B), carbide (M7C3), accompanied with a large amount secondary precipitations M23C6. Moreover, morphology hardness in ...

Deep cryogenic heat treatment is assumed as a supplementary heat treatment performed on steels before the final tempering treatment to enhance the wear resistance and hardness of the steels. In this study, the effects of the deep cryogenic heat treatment on the wear behavior and corrosion resistance of the 1.2080 tool steel were studied using the wear testing machine and polarization and impeda...

Hypereutectic High Chromium Cast Iron (HHCCI) is a new type of corrosion-wear-resistant material developed from ordinary high chromium cast iron by increasing the and carbon content often used in abrasive environments where wear corrosion interact. The resistance HHCCI related to number, size, shape distribution carbides microstructure matrix. This paper reviews research progress improving vari...
