A functional surface is an engineered system consisting of substrate and coating designed to work together. From a 50 µm thick diamond layer on cutting tools to a few atoms thin protective barrier on hard drives, a functional surface is a critical component in many new high technology products. It is the first line of defense of the coated part and thus, it is absolutely vital to the performance and to the reliability of the part in tough applications. This paper will present and critically review principles of surface engineering for cutting tools and wear parts. An emphasis will be on the design and preparation of the working surface as illustrated by case studies from diamond-coated cutting tools, thermal barriers for automotive and aerospace engines, concepts in cBN deposition, and recent developments in the field of nano-layer and nano-composite superhard films.
