Codeposition of Si, Al and Hf were prepared by pack cementation at 1300 °C for 10 h. The results show that the coating is composed of a thick (Nb, X)Si2outer layer, a (Ti, Nb)5Si4middle layer and a thin discontinuous (Cr, Al)2(Nb, Ti) inner layer. The mass gain of the coating is only 4.12 mg/cm2after isothermal oxidation at 1250 °C for 100 h. Some “oxide pegs” form at the interface of the oxide scale and coating. The coating exhibits good cyclic oxidation resistance due to the improved adhesion between the oxide scale and coating.
