Abstract:Iron-based amorphous alloy coating has become one of the most promising amorphous coating materials due to its good mechanical properties, excellent wear and corrosion resistance and low economic cost. This article reviews the design criteria and material system of iron-based amorphous coating materials, introduces the progress and development trend of iron-based amorphous coatings prepared by laser cladding technology and thermal spraying technology. The general situation of its engineering application is introduced combining with the performance characteristics of iron-based amorphous coatings. The current problems in the research field of ironbased amorphous coatings are pointed out and the development trend is prospected.
