| 摘 要： | 在实验室模拟了磨煤机实际服役工况，对比研究了HNM450耐磨钢与HARDOX450耐磨钢在磨煤机服役工况下的耐腐蚀磨损性能。在200 ℃高温、弱酸性(pH=5)或弱碱性(pH=9)且潮湿的环境中，河钢HNM450耐磨钢的耐腐蚀磨损性能均优于HARDOX450耐磨钢。同时，河钢HNM450耐磨钢和HARDOX450耐磨钢在弱碱性(PH=9)介质中耐腐蚀磨损性能均优于其在弱酸性(pH=5)介质中。

| Abstract: | The actual service conditions of coal mill were simulated in the laboratory. The corrosion resistance and wear resistance properties of wear resistant steels HNM450 and HARDOX450 were compared and studied. Under the conditions of high temperature at 200 ℃, weakly acidic (pH = 5) or weakly alkaline (pH = 9) and humid environment, the corrosion resistance and wear resistance of Hesteel HNM450 was better than that of HARDOX450. At the same time, both Hesteel HNM450 and HARDOX450 showed better corrosion resistance and wear resistance in weakly alkaline (pH = 9) medium than that in weakly acidic (pH = 5) medium. |
