Evaluation of the wear resistance of ZrN coatings using thin layer activation
Zirconium has an excellent biocompatibility and thus could be used for biomedical applications. However, its tribological properties are rather poor. In order to overcome this drawback, a zirconium nitride coating was prepared by thermal nitridation of Zircalloy-2. Wear tests using a pin on disk tribometer combined with gravimetry indicated a very good wear resistance. To obtain reliable numerical data and avoiding very long tests, the potential use of thin layer activation (TLA) in combination with a pin on disc tribometer was explored. The results indicate that TLA, in particular due to its high sensitivity, can provide important information regarding the surface degradation of these very wear resistant coatings.
