摘要：

Combined mode d.c.-r.f. sputtering was used to make deposits consiting of alternate layers of Ni/ZrO2 + Y or Ni-50 Cr/ZrO2 + Y with layer thicknesses ranging from 0.0048 to 0.0025 cm. Cyclic thermal shock testing and bend testing indicated that these deposits may be adherent to gas turbine airfoils and therefore may be useful for improving airfoil durability. It is expected that the ceramic layers will provide erosion/corrosion resistance (and possibly thermal insulation) while the metal layers provide the required mechanical properties, i.e. thermal expansion compatibility, resistance to impact damage and containment of the ceramic layers. When a metal overlayer is lost by erosion/corrosion, the ceramic layer (possibly extensively fractured) is expected to remain adherent to the next metal underlayer. © 1979.
