“…4c). This indicates that the Fe 2 B boride in directional Fe-3.5 wt.% B steel displays an obviously textured structure and that its preferred growth direction is the [002] orientation, which is consistent with previous investigation results [28][29][30]. boride in steel has a significant effect on the erosion-corrosion rate.…”

The interface characterization and erosion-corrosion behavior of directional Fe-3.5 wt.% B steel in the flowing zinc at 460ºC to 550ºC were investigated. The result indicated that directional Fe-3.5 wt.% B steel possesses better erosion-corrosion resistance to liquid zinc with the [002] orientation of Fe 2 B boride perpendicular to the erosion-corrosion interface. Liquid zinc temperature, Fe 2 B orientation in steel, and micromechanical scour have a significant effect on erosion-corrosion interface structure, which in turn governs the corrosion behavior of the matrix by influencing the dissolution and diffusion process, erosion-enhanced corrosion, the Fe 2 B boride failure mode, and further erosion-corrosion resistance.

“…With the addition of W in α-Fe, the corrosion resistance of the matrix is improved due to the lower atomic mobility of W. The maximum W fraction in Fe 2 B is about 14 wt % for the A6 alloy. As in Huang’s research, with the addition of tungsten the fracture toughness and the hardness of Fe 2 B were improved [ 19 ].…”

“…The excellent corrosion resistance of these alloys is mostly due to the high melting point and weak chemical affinity of such refractory materials with zinc. Xing et al [ 19 ] investigated the effects of tungsten on the microstructure and fracture toughness of the Fe 2 B phase in a Fe-B-C cast alloy. The results showed that the Fe 2 B still displayed a reticular morphology and the fracture toughness was greatly increased with tungsten addition.…”

The effects of tungsten addition on the microstructure and corrosion resistance of Fe-3.5B alloys in a liquid zinc bath at 520 °C were investigated by means of scanning electron microscopy, X-ray diffraction and electron probe micro-analysis. The microstructure evolution in different alloys is analyzed and discussed using an extrapolated Fe-B-W ternary phase diagram. Experimental results show that there are three kinds of borides, the reticular (Fe, W)2B, the rod-like (Fe, W)3B and flower-like FeWB. The addition of tungsten can refine the microstructure and improve the stability of the reticular borides. Besides, it is beneficial to the formation of the metastable (Fe, W)3B phase. The resultant Fe-3.5B-11W (wt %) alloy possesses excellent corrosion resistance to liquid zinc. When tungsten content exceeds 11 wt %, the formed flower-like FeWB phase destroys the integrity of the reticular borides and results in the deterioration of the corrosion resistance. Also, the corrosion failure resulting from the spalling of borides due to the initiation of micro-cracks in the grain boundary of borides is discussed in this paper.

“…Z.F. Huang found the microhardness of Fe 2 B is about 1500 HV [31], furthermore, J. Lentz found the hardness of the M 2 B is lightly higher than that of the Fe 2 B [32,33]. The hardness of M 7 C 3 is reported to be about 1800 HV by Tassin [34].…”

In this study, a high aluminum and chromium Fe-B-C coating was prepared using laser cladding on 2Cr13 steel substrate. The microstructure, microhardness, and wear resistance of the high aluminum and chromium Fe-B-C coating were investigated. The results show that this dense coating possesses good metallurgical bond with the substrate. The microstructure is mainly composed of α-(Fe, Cr, Al) lath martensite, orthorhombic M2B boride, orthogonal M3C2, and orthorhombic M7C3 carbides. The microhardness of the coating can reach 620 HV which is 3.3-times higher than that (190 HV) of the substrate. The coating shows a lower friction coefficient of 0.75 than that of the substrate (1.08). The wear rates of the substrate and the coating are 0.295 mg/min and 0.103 mg/min, respectively, indicating the coating exhibits excellent wear resistance. The wear mechanism transforms severe adhesive wear and abrasive wear of the substrate to slight abrasive wear of the coating. The results can provide technical support to improve the properties of the Fe-based laser cladded coating.
