Abstract: In one aspect, articles are described comprising wear resistant coatings employing composite architectures including refractory layers of varying compositions and phases. Briefly, a coated article comprises a substrate and a coating deposited by chemical vapor deposition (CVD) adhered to the substrate, the coating comprising an inner refractory layer comprising M1-xAlxN wherein x≥0.7 and M is titanium, chromium or zirconium and an outer zirconia layer or outer multiphase refractory layer comprising an alumina phase and an oxide phase comprising at least one Group IVB metal, wherein the M1-xAlxN has less than 15 weight percent hexagonal phase.
