Carbonitride coatings

CVD Diamond, Diamond-Like Carbon, and Carbonitride Coatings... 

AI2O3 is often used to provide a ceramic material in contact with the workpiece or to apply several multilayers of the type Al203/TiN. The thicknesses of the sublayers are on the order of about 1 pm and the total layer thickness is about 10-12 pm. Such a structure is shown in Fig. 29 for the WIDIA grade TNI 50. Most of these layers are deposited by CVD. Also a combination of PVD and CVD ( duplex ) techniques was studied and has yielded better performing layers than other titanium nitride and carbonitride coatings [110].
