As its name suggests, in this process the coating forms a chemical bond with the substrate. Therefore, the adhesion to the substrate is very strong. With CVD it is possible to create a thick coating of 5 to 25 microns. Due to its thicker layer, CVD provides excellent heat insulation and enables achieving higher cutting speeds compared with PVD. The downside is more sensitivity to cracks and fractures.
