High-wear-resistance Fe-B-W coatings were fabricated on 65Mn steel substrates via ultra-high-speed laser cladding by regulating boron content. The effects of boron content on the microstructure, microhardness and tribological properties of Fe-B-W coatings were systematically investigated by using scanning electron microscopy, X-ray diffraction, microhardness tester and friction and wear tester. The results reveal that the Fe-B-W coatings are mainly composed of α-Fe phase and Fe2B phase, along with a small amount of W phase, Fe3B phase and Fe23 B6 phase. Iron-boron compounds increase with the rising boron content, distribute in a network structure inside the coatings and gradually coarsen. The Fe-B-W coatings can greatly elevate the microhardness and wear resistance of 65Mn steel substrate. As boron content increases, the microhardness of the coatings rises gradually, while the friction coefficient and volumetric wear rate first decrease and then increase. The coating with 3.5% boron exhibits the lowest friction coefficient, and its volumetric wear rate also drops to the lowest, only 35.8% of that of the substrate, which demonstrates that Fe-3.5B-30W coating possesses optimal comprehensive performance. It is shown that the dominant wear mechanism of Fe-B-W coatings is abrasive wear.

通过调控硼含量,在65Mn钢基体上实现了高耐磨Fe-B-W涂层的超高速激光熔覆。采用扫描电镜、X射线衍射仪、显微硬度计和摩擦磨损试验机系统研究硼含量对Fe-B-W涂层微观组织、显微硬度和摩擦磨损性能的影响。结果表明,Fe-B-W涂层由α-Fe相、Fe2B相以及少量W相、Fe3B相和Fe23B6相组成,铁硼化合物含量随着硼含量增加而增加,并在涂层中呈网状分布,且逐渐粗化。Fe-B-W涂层能显著提高65Mn钢基体的显微硬度,并提高其耐磨性。随着硼含量增加,涂层的显微硬度逐渐增大,但其摩擦因数和体积磨损率先减小后增大,硼含量3.5%时,涂层具有最小的摩擦因数和最低的体积磨损率,此时其体积磨损率减小至基体体积磨损率的35.8%,表明Fe-3.5B-30W涂层具有更好的综合性能。Fe-B-W涂层的主要磨损机制是磨粒磨损。

通过调控硼含量,在65Mn钢基体上实现了高耐磨Fe-B-W涂层的超高速激光熔覆。采用扫描电镜、X射线衍射仪、显微硬度计和摩擦磨损试验机系统研究硼含量对Fe-B-W涂层微观组织、显微硬度和摩擦磨损性能的影响。结果表明,Fe-B-W涂层由α-Fe相、Fe2B相以及少量W相、Fe3B相和Fe23B6相组成,铁硼化合物含量随着硼含量增加而增加,并在涂层中呈网状分布,且逐渐粗化。Fe-B-W涂层能显著提高65Mn钢基体的显微硬度,并提高其耐磨性。随着硼含量增加,涂层的显微硬度逐渐增大,但其摩擦因数和体积磨损率先减小后增大,硼含量3.5%时,涂层具有最小的摩擦因数和最低的体积磨损率,此时其体积磨损率减小至基体体积磨损率的35.8%,表明Fe-3.5B-30W涂层具有更好的综合性能。Fe-B-W涂层的主要磨损机制是磨粒磨损。

High-wear-resistance Fe-B-W coatings were fabricated on 65Mn steel substrates via ultra-high-speed laser cladding by regulating boron content. The effects of boron content on the microstructure, microhardness and tribological properties of Fe-B-W coatings were systematically investigated by using scanning electron microscopy, X-ray diffraction, microhardness tester and friction and wear tester. The results reveal that the Fe-B-W coatings are mainly composed of α-Fe phase and Fe2B phase, along with a small amount of W phase, Fe3B phase and Fe23 B6 phase. Iron-boron compounds increase with the rising boron content, distribute in a network structure inside the coatings and gradually coarsen. The Fe-B-W coatings can greatly elevate the microhardness and wear resistance of 65Mn steel substrate. As boron content increases, the microhardness of the coatings rises gradually, while the friction coefficient and volumetric wear rate first decrease and then increase. The coating with 3.5% boron exhibits the lowest friction coefficient, and its volumetric wear rate also drops to the lowest, only 35.8% of that of the substrate, which demonstrates that Fe-3.5B-30W coating possesses optimal comprehensive performance. It is shown that the dominant wear mechanism of Fe-B-W coatings is abrasive wear.
