Fundamentals of Coating Technologies

Coating technologies for carbide tools fall into two broad contributions: Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD). Each has distint providents and is appropried to different applications. Understanding their ir underlying principles is essential for selecting the right coating for a given maching preseno.
