摘    要
为了研究提高轧辊使用寿命的方法，在轧辊常用材料5CrMnMo钢表面采用高速激光熔覆技术，分别熔覆了Fe基、Ni基、Co基合金涂层。采用扫描电镜、硬度仪测试了涂层的组织与硬度，并对涂层进行高温压缩测试、热冲击测试和高温磨损测试，以研究其耐高温磨损性能。结果表明，涂层随温度的升高其硬度均有一定程度的降低。Fe基、Ni基涂层在高温压缩与热震测试中未发现开裂、脱落现象。从磨损失重角度而言，Fe基重熔涂层与加入硬质相的Fe基涂层能够发挥较好的高温耐磨性能，其在300 ℃下的摩擦磨损形式为磨粒磨损和黏着磨损。3种涂层均具有较高的耐高温磨损性能。

Abstract
In order to study methods to prolong the service life of rolls, high-speed laser cladding was used on the surface of 5CrMnMo steel, a commonly used material for rolls, and Fe-based, Ni-based, and Co-based alloy coatings were respectively deposited. The microstructure and hardness of the coatings were tested using a scanning electron microscope and a hardness tester. The coatings were subjected to high-temperature compression testing, thermal shock testing, and high-temperature wear testing to investigate their high-temperature wear resistance properties. The results indicated that the hardness of the coatings decreases to a certain extent with the increase of temperature. No cracking or peeling phenomenon was found in the Fe-based and Ni-based coatings during high-temperature compression and thermal shock tests. From the perspective of wear loss, Fe-based remelted coatings and Fe-based coatings with added hard phases could exhibit good high-temperature wear resistance. Their frictional wear mechanism at 300 ℃ were abrasive wear and adhesive wear. All three coatings have excellent high-temperature wear resistance.
