“…Corrosion behavior of refractory metals and ceramics in molten LBE and lead has been investigated. Refractory metals of tungsten and molybdenum [10,17,19], and ceramics of SiC [10,11,19] and Ti 3 SiC 2 [10,20,21] was reported good corrosion resistance in the lead alloys.…”

“…Certain MAX phases have been tested for corrosion in select coolant environments. For example, it has been shown that Ti 3 SiC 2 has superb corrosion resistance to molten Pb and Pb-Bi alloys [20,21]. The diffusion between Zircaloy-4 and the MAX phases Ti 3 SiC 2 and Ti 2 AlC in the 1100-1300 • C range has also been explored [22].…”

a b s t r a c tHerein we report on the reactivity between silicon carbide, SiC, and pyrolytic carbon, PG, with the MAX phases, Ti 2 AlC, Ti 3 AlC 2 , Ti 3 SiC 2 and Cr 2 AlC. Diffusion couples were assembled and heated to 1300 • C under a load corresponding to a uniaxial stress of ∼30 MPa for 4, 10, and 30 h in a vacuum hot press, at a vacuum level of less than 1 Pa. The couples were then examined using optical and scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, and orientation image microscopy. Based on the totality of the results -after 30 h at 1300 • C -it is concluded that neither Ti 3 SiC 2 nor Cr 2 AlC appear to react with SiC. The former also appears not to react with PG. When heated in the vacuum of the hot press, both Ti 2 AlC and Ti 3 AlC 2 dissociated to form TiC surface layers that were ≈15-20 m thick. After reaction of Ti 2 AlC with SiC and PG, the TiC layer was only ≈10 m thick, indirectly confirming that the dissociation of these phases in vacuum was due to the Al evaporation from the surfaces. The Ti 3 AlC 2 /SiC and Ti 3 AlC 2 /PG diffusion couples resulted in TiC layers that were ≈50 m and ≈100 m thick, respectively. The Cr 2 AlC/PG diffusion couple resulted in the formation of ≈10 m interfacial layer comprised of Cr 3 C 2 and Cr 7 C 3 at the interface between the two materials.
