Abstract
A coated article having a high resistance to particle-impact damage has a substrate, and a layered coating overlying the substrate. The layered coating includes a substantially continuous quasicrystalline layer, and a substantially continuous ductile metallic layer in facing contact with the quasicrystalline layer. The coated article is preferably used in applications where it is subjected to particle-impact conditions.
