Abstract: A coated article that includes a substrate and a wear-resistant coating scheme. The coated article may be a cutting insert shown to improve performance in chip-forming material removal operations or a wear-resistant component used in chipless forming operations. The wear-resistant coating scheme has an underlayer and top layer containing aluminum, chromium, and nitrogen. The coating scheme also includes a mediate multi-periodicity nanolayer coating scheme containing titanium, aluminum, chromium and nitrogen. The mediate multi-periodicity nanolayer coating scheme includes a plurality of sets of alternating layer arrangements. Each one of the alternating layer arrangements has a base layer comprising titanium, aluminum and nitrogen and a nanolayer region having a plurality of sets of alternating nanolayers. Each set of alternating nanolayers has one nanolayer having aluminum, chromium, titanium and nitrogen and another nanolayer having aluminum, chromium, titanium and nitrogen.
