In this study, the adhesion strength of niobium nitride (NbN) coatings was investigated using both PLST and MPST.
In this context, I have investigated the adhesion properties of NbN coatings that were deposited by pulsed dc magnetron sputtering using different target currents during PLST and MPST tests.
To analyze the influence of the target currents on adhesion, the substrate-coating adhesion using PLST and MPST was investigated by means of a Revetester from CSM Instruments.
14), (15) To confirm the nature of the fatigue failure of the coatings deposited at different target currents, MPST were carried out at a sub-critical loading set to 30 N.
7a, slight spallation occurred during MPST after 50 cycles and this spallation increased with increasing the number of cycles (300 cycles).
