摘要： Zirconia-containing ceramic compositions having a c/a ratio of the zirconia lattice in the range of from 1.005 to 1.016. These compositions comprise a stabilizing amount up to 10 mole % of the composition of a stabilizer component which comprises: (1) a first metal oxide selected from the group consisting of yttria, calcia, ceria, scandia, magnesia, india and mixtures thereof in an amount of from 1.5 to 6 mole % of the composition of; (2) a second metal oxide selected from the group consisting of lanthana, neodymia and mixtures thereof in an amount of from 0.5 to 4 mole % of the composition; and (3) optionally ytterbia in an amount of from 0.5 to 4 mole % of the composition. These compositions further comprise hafnia in an amount of from 0.5 to 15 mole % of the composition; and optionally tantala in an amount of from 0.5 to 1.5 mole % of the composition. These compositions are useful in preparing thermal barrier coatings (22) having a balance of reduced thermal conductivity with good producibility, spallation resistance and erosion/impact resistance for an underlying metal substrate (14) of articles (10) that operate at, or are exposed to, high temperatures.

摘要： A PVD process and apparatus (120) for depositing a coating (132) from multiple sources of materials with different vapor pressures. The process entails forming molten pools (114,115) of different first and second materials in a coating chamber (122) of the apparatus (120), supporting an article (130) within the chamber (122), and evaporating the molten pools (114,115) with an energy beam (126) to deposit a coating (132) on the article (130) with a controlled composition that contains at least a first metal and a relatively lesser amount of at least one reactive metal having a lower vapor pressure than the first metal. The first material contains at least the first metal, and the second material contains the reactive metal and at least a second metal. The second and reactive metals are combined to cause the second material to have a lower melting temperature and wider melting range than the reactive metal.

The component typically further comprises a ceramic thermal barrier coating overlying the protective coating (24). Also disclosed are methods for forming a protective coating system on the turbine engine component by forming the non-metallic oxide or nitride diffusion barrier layer (28) on the substrate (22) and then depositing the platinum group metal on top of the barrier layer (28).
