“…However, the poor wear and corrosion resistances of Ni-based coatings fabricated by LC limits their wide applications in harsh environments. In order to avoid such disadvantages, adding alloy elements (such as Cr, W, Mo), rare earth oxides (such as Y2O3, CeO2, La2O3) or secondary reinforcing phases (such as SiC, WC, B4C, TiC) are usually adopted to further improve the wear and corrosion resistances of Ni-based coatings fabricated by LC [13][14][15][16]. Moreover, improving the process of LC, such as laser induction hybrid cladding [17], is also another way to strength the properties of Ni-based coatings, but the device is complicated.…”

To enhance the wear resistance and corrosion resistance of Ni-based coatings, carbon fibers reinforced nickel-based composite coatings (CFs/Ni) were fabricated on the surface of 1Cr13 stainless steel by laser cladding (LC). The microstructure characteristics, microhardness, wear and corrosion performances of the composite coatings were investigated. The results show that CFs can effectively improve the corrosion and wear resistances of Ni-based coatings. With increasing laser scanning speed, the morphology of CFs in composite coatings is more integral and the corrosion

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.

“…Wear resistance of these coatings is all greatly improved when compared with that of titanium alloys due to their very high hardness of about 750-1400 HV resulting from a combination of the refinement/solution/dispersion strengthening effects. However,the intermetallic compounds involved in the above-mentioned composite coatings will bring about some new issues, such as poor machinability and high cracking susceptibility [21,22]. In addition, the further improvement in their comprehensive properties is also greatly restricted by the main components.…”

TiAlCoCr x FeNihigh-entropy alloys (HEAs) coatings were fabricated on the surface of Ti6Al4V by laser cladding. Their microstructural evolution with the increase in x value (x=0, x=1.0, x=2.0) was investigated in detail. Besides that, the investigation into the effects of the Cr content on their corrosion behaviors and mechanical properties (in terms of hardness and wear resistance) was also carried out comprehensively. The results indicated that two kinds of phases (a solid solution with thehexagonal close-packed (HCP) structureand Ti 2 Ni) were synthesized in the coatings, and the HCP content was gradually increased with the increase in x accompanied with the decrease in Ti 2 Ni content. A HEA coating only composed of single HCP was successfully prepared when x reached 2.0. The electrochemical and immersion tests all confirmed that the coating with x=2.0demonstrated the most excellent corrosion resistance in a0.1 mol·L −1 HCl solution from different aspects including corrosion tendency and corrosion rate without the applied potential, the formation difficult/stability of the passive film and the dissolution rate in the passive state, and corrosion surface morphology. The averagemicrohardness values of the coatings weregraduallyincreasedfrom 656HV 0.2 to 800 HV 0.2 with increasing xfrom 0 to 2.0, which wereabout double that of the substrate (350 HV 0.2 ). Wear resistance of the coatings also exhibited the upward tendency with increasing the x values (0.562 mm 3 at x=2.0, 0.640 mm 3 at x=1.0, 0.641 mm 3 at x=0 and 1.419 mm 3 for the substrate). More Cr addition into the cladding material will contribute to the formation of a HEA coating composed of single HCPwith excellent corrosion and wear resistance.
