【 摘 要 】

The oxidation behaviours of ZrN, TiN and TiSiN in a steam environment in the high temperature range of 600-900 degrees C have been studied and compared. Nitride coatings were deposited by reactive magnetron sputtering onto Zirc - alloy and silicon wafer substrates. The steam oxidation test was performed in order to investigate oxidation resistance in the Loss - of - Coolant Accident (LOCA) scenario in Light Water Reactor applications. It was found that TiSiN showed better oxidation resistance in a steam environment than ZrN and TiN. Coatings in the as-deposited state and after thermal exposure were characterised using focused ion beam, transmission electron microscopy and X-ray diffraction to evaluate microstructure and phases present in the coatings.
