Analysis of Performance of Detonation Spraying Al2O3 Coat

    Graphical Abstract
    • Abstract
  • Al2O3 coat is prepared via detonation spraying with NiAl powder as ground floor and 45 steel as base.XRD spectrum of the coat indicates that structure are α-Al2O3 and γ-Al2O3 mainly,indicating the structure changed.The porosity of the coat is 0.019 n/ mm2 by JB/T 7509-94 iron reagent,indicating the coat has denser microstructure and fewer porosity,this suggests that the detonation spraying coat can improve the wear resistance of base steel and is suitable for wear resistance coat.
