“…One of important advantages of these ternary carbides is that they readily machinable with nothing more sophisticated than a manual hack saw [22]. Compatibility of Ti 3 SiC 2 in high temperature lead in this investigation agrees with the other reports [10,20,21].…”

“…However, in flowing lead-bismuth at 550°C it was reported that cracks on the surface layer of SiC specimen with 25 mm in depth [11]. Recently, investigations of a new type of ceramic, Ti 3 SiC 2 , in high temperature lead alloys have been reported [10,20,21]. One of important advantages of these ternary carbides is that they readily machinable with nothing more sophisticated than a manual hack saw [22].…”

Tribological property of c-axis textured shell-like Ti 3 AlC 2 ceramic was investigated using reciprocating sliding balls (SUS304) under loads of 1, 5, and 9 N. It was found that the textured top surface (TTS), corresponding to the (000l) plane, shows the lowest mean coefficient of friction in comparison with those measured on the textured side surface (TSS), where the sliding directions are parallel (TSS-1) and perpendicular (TSS-2) to c axis, under the same load. Among all the tested orientations, the TSS-2 exhibited the lowest wear rate of 1.51×103 mm 3 /(N·m) under the load of 9 N.The worn mechanisms on the TTS and TSS-1 were delamination, grain fracture, and grain spalling-off. On the TSS-2, plowing effect against balls was the dominating mechanism. This work suggests the criteria to maximize the wear resistance in the load range of 1-9 N.

“…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.
