TiN Coatings on Fuel Cladding Tube
Abstract
In this study, TiN coatings were deposited on HT-9 and MA957 stainless-steel tubes and polished bars. In order to deposit TiN coatings on those certain length tubes, we need to modify our stage in old chamber. We designed a stage which can move along with XYZ axis’s direction and also can do rotation with the speed at 10 circles per minute. The flange we designed would be mounted to the 12 inch chamber obtaining ultra-high vacuum. After designing and setting up the instruments, we would demonstrate this new design and deposite TiN on the tubes. A systematic physical property study including surface characterization (SEM), mechanical testing (hardness and scratch test), thermal cycle test and thermal conductivity measurements, was conducted to explore the effects of the coatings on the overall mechanical, thermal stability and thermal conductivity of the fuel cladding materials. A preliminary diffusion barrier study of Ce in HT-9 with and without the coating was also conducted.
