Abstract Scope |
Coated SiC-SiC Composite Material has been proposed as a possible accident tolerant cladding material. To select the right coating, several coatings such as ZrN, TiN, Ti/TiN, TiC, and a Zr-Cr-Ti tri-layer were envisioned either by Chemical Vapor Deposited (CVD) or Physical Vapor Deposited (PVD). As-received and heat treated samples of the best candidates were subjected to simulated boiling water reactor conditions (288 ˚C, 1100 psi, and 2 ppm DO). Corrosion was quantified using a high precision balance to track weight changes after various times in the autoclave. Post-experiment analysis was performed with Secondary Ion Mass Spectroscopy (SIMS), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM) equipped with Energy Dispersive Spectroscopy (EDS) detectors. Mechanical testing was also employed to test the adherence of each coating. |
