A method of depositing a bond coating to a surface of an article includes the steps of depositing an inner layer of the bond coating consisting of beta-NiAl comprising Fe, Ga, Mo, B, Hf or Zr or gamma/beta-MCrAlY comprising Fe, Ga, Mo, B, Hf or Zr or gamma/gamma'- or gamma-MCrAlY, and depositing an outer layer of the bond coating, which is more coarse the in the inner layer, consisting of beta-NiAl comprising Fe, Ga, Mo, B, Hf or Zr or gamma/beta-MCrAlY comprising Fe, Ga, Mo, B, Hf or Zr or gamma/gamma'- or gamma-MCrAlY, wherein said elements Fe, Ga, Mo, B, Hf or Zr above mentioned are present individually or in combination. The coating also includes a noble metal selected from the group consisting of platinum, palladium and rhodium in the inner and outer layer or as a separate layer.
