NANO-LAYER COATING FOR HIGH PERFORMANCE TOOLS

摘要

The present invention relates to a coated body comprising a substrate and a coating onto the substrate, the coating having a nanolaminated coating system having a nanolaminated coating structure of alternating A and B layers (AlxTi1-x-yWy)N/(Ti1-z-uSizWu)N, the individual thickness of each nanolayer being maximal 200 nm and the nanolaminated coating structure exhibiting a fine-grained structure.
