Abstract
A procedure increasing the accuracy of determining the delamination coefficient of coatings and simplifying the investigation into the adhesion strength of ion-vacuum coatings is considered. When developing the deposition technology, determining the thick- ness, and correcting the coating composition, the method of determining the surface area of coating delamination from the base after diamond indentation using a Rockwell hardness meter at a load of 150 kgf is simplest and most efficient. The method is based on the DIN German-VDI 3198 German Standard for CVD and PVD coatings. A procedure for calculating the surface area of coating delamination after indentation using Adobe Photoshop CS3 and kaloSOFT Version 3.54e is presented. A correlation of the delamination coefficient with the adhesion strength of the TiN coating with the WC base is revealed.
