Abstract
A coated article having a high resistance to wear damage has a substrate, and a layered coating overlying the substrate. The layered coating includes a ductile metallic layer overlying and in facing contact with the substrate, and a protective layer overlying and in facing contact with the ductile metallic layer and including a mixture of a quasicrystalline metallic phase and a non-quasicrystalline ductile phase. The coated article is preferably used in applications where it is subjected to wear conditions.
