Summary:Title screen
Titanium nitride coatings were deposited by reactive dc magnetron sputtering (dcMS) to protect Zr-1Nb alloys from hydrogen embrittlement. Dense titanium (Ti) interlayer was prepared between TiNx protection film and a Zr substrate to improve thermal stability and adhesion between the TiNx and the substrate at high temperatures. Hydrogen absorption of Zr- 1Nb with TiNx and Ti/TiNx at 623 K was reduced in comparison with uncoated Zr-1Nb. No peeling or cracks of Ti/TiNx coatings is observed after thermal cycling up to 1073 K. The high temperature (1073 K) hydrogenation behaviour differs from the hydrogenation at lower temperature by increasing the amount of dissolved hydrogen in the phase of zirconium. The higher rate of hydrogen absorption by Zr-1Nb with TiNx was observed due to the coating delamination as a result of differences in thermal expansion coefficients, while Ti/TiNx demonstrates the lower hydrogen absorption at 1073 K and good adhesion strength.
