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. The base layer has a base layer thickness and the nanolayer region has a nanolayer region thickness. The base layer thickness is smaller than the nanolayer region thickness.
