AB  - Fe-based amorphous/nanocrystalline coatings were prepared on the AISI 321 steel 
      substrate by the high-velocity oxygen-fuel (HVOF) thermal spraying technology. 
      The effect of selected parameters (oxygen flow, kerosene flow and spray distance) 
      on the cavitation erosion resistance (denoted as Rc) of the coating were 
      investigated by using the Taguchi method. Statistical tools such as design of 
      experiments (DOE), signal-to-noise (S/N) ratio and analysis of variance (ANOVA) 
      were used to meet the expected objective. It was concluded that the kerosene flow 
      had greater influence on the Rc of the coating and followed by the spray distance 
      and the oxygen flow, respectively. The optimum spray parameters (OSP) were 
      963L/min for the oxygen flow, 28L/h for the kerosene flow, and 330mm for the 
      spray distance. The Rc of the coating increased with the increase of hardness or 
      the decrease of porosity, and the hardness had a greater influence on Rc than the 
      porosity. The Fe-based coating deposited under the OSP exhibited the best 
      cavitation erosion resistance in distilled water. The cracks initiated at the 
      edge of the pores and the interfaces between the un-melted or half-melted 
      particles, and finally leaded to the delamination of the coating.
