| Abstract: |
| Fe-based amorphous alloys have exceptional properties, such as high strength, high hardness, good wear resistance, and corrosion resistance, and have important applications in the fields of tribology and corrosion resistance. However, the relatively poor glass-forming ability of Fe-based amorphous alloys and their inability to be prepared in large blocks at room temperature due to their brittleness greatly limit their application as bulk materials. To effectively address this problem, the excellent properties of Fe-based amorphous alloys can be demonstrated in the form of coatings. The Fe-based amorphous coating can overcome the restrictions of size and room temperature brittleness, and its excellent properties such as high wear resistance and high corrosion resistance will be well utilized. This will improve the surface properties of the matrix material and significantly widen the range of applications for Fe-based amorphous alloys. This paper summarized the design criteria for amorphous alloy components and coating material systems in a more systematic way. The influence mechanism of thermal spraying and laser cladding technology on the properties of Fe-based amorphous coatings was analyzed，and the progress of research and application of wear resistance and corrosion resistance of Fe-based amorphous coatings were reviewed. The prospect of Fe-based amorphous coatings with high wear and corrosion resistance for application on aircraft carrier flight deck and other engineering was also discussed. In addition, the current application status and problems with Fe-based amorphous coatings were introduced, and it is predicted where they will go in terms of future development. An amorphous alloy is a type of metastable material that is extremely sensitive to composition. A slight variation in composition can result in a significant difference in glass-forming ability. Various compositional design criteria for amorphous alloys have been proposed and applied to improve the glass-forming ability. The incorporation of multiple metallic elements can improve the Fe-based amorphous formation ability due to their size differences and different negative mixing enthalpies, resulting in an increase in the entropy and long-range disorder of the system, which improves the amorphous formation ability. There are various factors affecting the wear and corrosion resistance of the coatings, such as the preparation process, elemental composition, amorphous content, porosity, surface roughness, hardness, and subsequent treatment of the coatings. The SAM series of Fe-based amorphous coatings has been developed abroad. On this basis, the non-skid deck coating for the warship has been developed. Due to the innovation in the spraying method, the surface of the coating after spraying has a special texture, and the coating has a high coefficient of friction, high abrasion resistance, impact resistance and corrosion resistance that are all superior to the existing organic non-skid coating. The high coefficient of friction is necessary to ensure that employees can perform their jobs on the deck normally. The main challenge to breaking through the technical blockade is the development and preparation of more Fe-based amorphous coating systems with high wear resistance and corrosion resistance, given the current state of domestic research. In China, the plungers of water injection pumps have already been coated with Fe-based amorphous materials by businesses, and the wear resistance is still strong even in extremely corrosive conditions. By applying the same Fe-based amorphous coating to boiler water-cooled wall panels, the equipment can have a 10-fold increase in service life. Currently, Fe-based amorphous coatings are used in the military, aerospace, marine protection, nuclear industry, storage and combustion, tunnel boring machines, boiler wall protection, and other fields. |
