چکیده
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 change little, while volume fraction increases from 16.23% to 23.16%. This effectively 64.53±0.50 HRC 66.58±0.50 HRC, result possesses better compared center position. Furthermore, wear mechanism changes micro-plowing micro-cutting increase hardness.
