Abstract:
Fe-based amorphous alloy coating has become one of the most promising amorphous coating materials with excellent comprehensive properties and low economic cost. The concept and application of Fe-based amorphous alloy coating were reviewed. The preparation state of Fe-based amorphous alloy coating was introduced with plasma spraying, arc spraying and laser cladding coatings. The mechanical properties of the coatings, such as hardness and residual stress, were discussed.The studies show that increasing the content of amorphous phase, introducing ceramic particles and optimizing the coating structure can improve the wear and corrosion resistance of the coating. The porosity of the coating has a crucial influence on the wear resistance and corrosion resistance of the coating. The sealing treatment can effectively reduce the porosity and improve the coating quality. The Fe-based amorphous alloy coating has broad application prospects and needs further research and optimization to meet the needs.
