Dislocator Chemistries for Turbine Abradable or Machinable Coating Systems

A coated article (20;60) includes a substrate (22) and a coating (24;62) on the substrate. The coating includes at least a first layer (30). The first layer has: a matrix (50); and a filler (52) at 2.0% to 40% by volume in the first layer. The first layer is selected from alkaline earth or transitio...

Zusammenfassung:	A coated article (20;60) includes a substrate (22) and a coating (24;62) on the substrate. The coating includes at least a first layer (30). The first layer has: a matrix (50); and a filler (52) at 2.0% to 40% by volume in the first layer. The first layer is selected from alkaline earth or transition metal (M) tungstates (MWO4); alkaline earth molybdates (MMoO4); rare earth (RE) phosphates (REPO4); and combinations thereof.
