“…The coating prepared by this technology has fewer impurities, less residual stress and higher bonding strength of the coating. 32 The spray distance in flame spraying is closely related to the melting degree of the particles and the time the particles stay in the flame. 33 Liu et al 34 prepared Fe-based amorphous coatings by HVOF and studied the effect of spraying distance on the coating quality.…”

Compared with crystal alloy, amorphous alloy features atomic arrangement of long-range disorder and near-range order; it has no crystal boundary, dislocation and other defects that can easily promote corrosion initiation and development. With good mechanical properties, wear resistance and corrosion resistance properties, today amorphous alloys have become a research hotspot worldwide. However, the amorphous formation ability is limited, which restricts large-scale preparation, popularization and application of three-dimensional block materials. Due to the technical characteristics of rapid solidification, laser cladding technology and spraying technology are beneficial to the efficient preparation and transformation of amorphous alloy in the form of coating materials. According to the current research progress of amorphous and nanocrystalline composite coatings, this article introduces the typical amorphous and nanocrystalline composite coating alloy systems, summarizes the research progress of preparing amorphous and nanocrystalline composite coatings and expounds the research situation of the main mechanical properties, wear resistance and corrosion resistance of amorphous and nanocrystalline composite coatings. Finally, the application scope of amorphous and nanocrystalline composite coatings is reviewed, and the current problems and future development trends in the study of amorphous and nanocrystalline composite coating are indicated.Zhibin Zhang and Jiachi Yuan have contributed equally to this work.
