Study of NiCrAlCoY Coating Prepared by Mechanical Alloying AITranslate
Abstract AITranslate
NiCrAlCoY coating was obtained at room temperature on the carbon steel surface with a high-energy ball mill.SEM,EDS,XRD,microhardness test technique and high-temperature oxidation experiment were employed to investigate morphology,structure,microhardness and high-temperature oxidation resistance of the coating.Coating formation mechanism on substrate surface is discussed in the process of mechanical alloying.The results show that increasing ball rotation speed can improve the thickness,microhardness and high-temperature oxidation resistance of the coating.A 50 μm thick NiCrAlCoY coating combined well with substrate is formed by ball milling at 400 r/min for 10 h.The maximum microhardness（HV0.1） of the coating reaches 706,about three times as high as that of the substrate.Interface microhardness presents gradient variation,playing a good role in supporting the coating.And the high-temperature oxidation resistance of substrate is improved significantly in the presence of the coating.
