| 耐磨钢/碳钢复合板不仅具有高强耐磨的双重性能优势，还可以降低能耗及生产成本。针对不同淬火工艺研究该复合板耐磨层NM500的耐磨性，对NM500/Q345复合板进行不同淬火温度下的干滑动摩擦磨损试验。借助显微硬度计测量试样表面的硬度，利用扫描电子显微镜(SEM)、白光干涉三维表面轮廓仪等分析该复合板耐磨层NM500的金相组织、磨痕的宏/微观形貌以及磨损机理。研究结果表明，当淬火温度为860~920 ℃时，淬火前后的硬度差别很大，淬火后的试样相比淬火前的试样硬度有很大的提高，随温度的上升先增加再降低，在温度为880 ℃时达到最高;摩擦因数曲线完全符合标准的干滑动摩擦磨损曲线，先快速上升然后有一定程度下降，最后趋于平稳;淬火后的磨损体积相比于淬火前会有很大程度减小，在淬火温度为860 ℃时，磨损量最少，耐磨性最好。 |

| Wear-resistant steel and carbon steel composite plate not only has the advantages of high strength and wear resistance, but also reduces energy consumption and production cost. The wear resistance of wear-resistant layer NM500 of composite plate was studied according to different quenching processes. The dry sliding friction and wear experiments of NM500/Q345 composite plate were carried out at different quenching temperature. The surface harness of specimen was measured by microhardness tester. The microstructure of wear-resistant layer, macro/micro morphology of wear scar and wear mechanism were analyzed by scanning electron microscope (SEM) and white light interference three-dimensional surface profiler. When the quenching temperature was between 860 ℃ and 920 ℃, there was a great difference in hardness before and after quenching. The hardness of the quenched specimen was much higher than that of the specimen before quenching. With the increase of temperature, the hardness firstly increased and then decreased, and reached the highest at 880 ℃. The friction coefficient curve was in line with the standard dry sliding friction wear curve, which rose rapidly and then decreased to a certain extent, and finally tended to be stable. The wear volume after quenching is greatly reduced compared with that before quenching. When the quenching temperature is 860 ℃, the wear amount is the least and the wear resistance reaches the best. |
