    chemical vapor deposition ( CVD)

    High-temperature (1,000° C or higher), atmosphere-controlled process in which a chemical reaction is induced for the purpose of depositing a coating 2µm to 12µm thick on a tool’s surface. See coated tools; PVD, physical vapor deposition.

A random arrangement is all well and good when it comes to avant-garde music, but the random crystal growth direction found in conventional CVD alumina cutting tool coatings can create weak areas where cracks form, shortening tool life.
