Abstract

Plasma spraying is being investigated as a method to fabricate first wall Be armor for the International Thermonuclear Experimental Reactor. Diffusion barriers of Ti, V, and W were deposited between the Be and the Cu substrate, also by plasma spray, to prevent formation of brittle Be-Cu intermetallics. Interface fracture toughness tests revealed loading mode-dependent crack behaviors and interface fracture toughnesses.
