Abstract
A method of forming a coated body having a nanocrystalline CVD coating of Ti(C,N,O) is disclosed. The coating is formed using the MTCVD process and including, as part of the gaseous mixture, CO, CO or mixtures therof. The use of this dopant during the coating results in a much smaller, equiaxed grain size.
