MEASUREMENT OF ADHESION STRENGTH OF Mo-Ti-N AND Mo-Сu-N COATINGS USING «SCRATCH-TESTER» DEVICE
Abstract
The new «scratch-tester» device for measurement of adhesion strength of coatings is presented. The device has a number of advantages as compared with known analogues – the expanded range of investigated sample sizes and more simple procedure of sample positioning, more precise measurement of scratching length, additional manner of registration of coating destruction or tearing off instant on the base of friction force. The device was used for investigation of Mo-Ti-N and Mo-Сu-N coatings on carbide cutting insert. It was found that Мо-Ti-N coatings have five times greater adhesion strength as compared with MoCu-N coatings.
