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.

“…Similar to metal, Ti 3 SiC 2 is electrically and thermally conductive, is relatively soft, and can be easily machined with standard tools. Similar to ceramic, Ti 3 SiC 2 is elastically stiff with relatively low hardness and light weight and can resist thermal shock, corrosion, and chemical attack [1][2][3][4][5]. Several researchers have studied the two-stage sliding friction and wear process using Ti 3 SiC 2 against various counterparts under dry sliding condition or its tribological behaviors under various solutions.…”

The tribological performance of Si3N4ball sliding against Ti3SiC2disc lubricated by lithium-based ionic liquids (ILs) was investigated using an Optimol SRV-IV oscillating reciprocating friction and wear tester at room temperature (RT) and elevated temperature (100°C). Glycerol and the conventional imidazolium-based IL 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (L-F106) were used as references under the same experimental conditions. The results show that the lithium-based ILs had higher thermal stabilities than glycerol and lower costs associated with IL preparation than L-F106. The tribotest results show that the lithium-based ILs were effective in reducing the friction and wear of Si3N4/Ti3SiC2contacts. [Li(urea)]TFSI even produced better tribological properties than glycerol and L-F106 both at RT and 100°C. The SEM/EDS and XPS results reveal that the excellent tribological endurance of Si3N4/Ti3SiC2contacts lubricated by lithium-based ILs was mainly attributed to the formation of surface protective films composed of various tribochemical products.

“…Within comparative sessions, the team was presented with various attributes that had extracted from a careful review of literature . Then, seven attributes for selecting the carbon source were obtained: • Cost ( A 1 ): Cost of carbon precursors in sol‐gel synthesis of TiC nanopowders plays a very significant role in selection of the best of them.…”

This article develops a new intuitionistic fuzzy multi-attribute group decision-making model to solve precursor selection problems. The proposed model is based on a hybridization of intuitionistic fuzzy sets theory, grey relational analysis and technique for order performance by similarity to ideal solution method. To better describe the uncertain decision environment, multi-attribute group decision-making method with completely unknown weights of both experts and attributes is proposed in an intuitionistic fuzzy setting. Finally, the selection of the carbon source in synthesis of nanocrystalline titanium carbide powders by sol-gel route as an application example is solved by the proposed model, and the implementation of the model is illustrated completely. *hashemi.h@live.com
