| Abstract Scope |
Current material options for construction of high-temperature components of nuclear reactors are limited in terms of those that may provide adequate corrosion resistance for the desired operating life. Materials such as austenitic stainless steel possesses excellent high temperature strength and lower cost, but exhibits poor corrosion resistance in molten fluoride salts. In this research, bi-layer and tri-layer coatings (including Ni, Mo, W, and Ta) on Alloy 617 substrates were fabricated using plasma enhanced magnetron sputtering (PEMS) and electrodeposition. High temperature fluoride molten salt testing was conducted at temperatures between 610 C to 850 C. Delamination and intergranular corrosion was assessed on the samples after exposure by optical microscopy. |
