Microstructure and Wear Resistance of a Ni–Fe–Si–B Amorphous Composite Coating by Laser Cladding
In this study, a Ni–Fe–Si–B amorphous composite coating is coated on H13 steel by laser cladding. Coatings are systematically investigated for their microstructure, phase composition, tribological behavior, and mechanical characteristics. X-ray diffraction results demonstrate that the cladding layer can be divided into the interface, transition, and compositionally stable zones, where the coating has both crystalline and amorphous phases, with up to 57% of the coating being amorphous. According to scanning electron microscopy and transmission electron microscopy analyses, the middle and surface regions of the coating mainly consist of (Fe0.5Ni0.5)3Si, Fe2B, Fe2NiB, Ni31Si12, and amorphous phases. The in-situ generated Fe2B phase is uniformly distributed within the coating, leading to a significant enhancement in microhardness. The greatest hardness of the coating is approximately 927.04 HV0.2. The composite coating exhibits excellent wear resistance, which is approximately 1.71 times greater than that of the substrate. Minor abrasive wear constitutes the primary wear mechanism for the coatings.
期刊介绍：
Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
