Abstract：The microstructure and tribological properties of Fe-based amorphous coatings which fabricated by air plasma spray (APS), high-velocity oxygen-fuel (HVOF) spray and detonation spray (DS) were compared. The relationships between spray technique, amorphous content, porosity and wear resistance behavior were investigated. Coating microstructure, cross-sectional morphology and friction surface morphology were observed by SEM. Amorphous structure of powder and coatings was examined by XRD. Wear resistance of coatings and stainless steel was tested by wear and abrasion equipment. The results show that the microstructures of the coatings are mainly composed of amorphous phase. The amorphous contents of the coatings made by various spray techniques are 79.39%, 85.26% and 88.14%, the porosity are 2.5%, 1.9% and 1.5% respectively. The detonation sprayed coating has the best wear properties, and the wear mechanism is typical fatigue wear. The coatings exhibit better wear resistance than the stainless steel substrate.
