摘要：

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 ZrN 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 avoid very long tests, the potential use of thin layer activation (TLA) in combination with a pin-on-disk 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.
