“…The inner is a continuous alpha-Al 2 O 3 layer, while the outer is a rutile TiO 2 layer [3,5,10]. Hot corrosion of MAX phases in molten salts was also reported by literatures [13][14][15][16]. For instance, Cr 2 AlC exhibits exceptionally good hot corrosion resistance against molten Na 2 SO 4 salt due to the formation of a protective Al 2 O 3 -rich scale at 800-1300 ℃ in air [7].…”

This paper investigated the corrosion behaviors of Ti 3 AlC 2 at 700 ℃ in molten KOH with various mass ratios. If the mass ratio of KOH:Ti 3 AlC 2 ≤2, Ti 3 AlC 2 can resist KOH hot corrosion in 2 h. Ti 3 AlC 2 suffered serious corrosion attack if the mass ratio≥3. The main compositions of corroded samples were amorphous graphite and potassium titanates (K 2 O·nTiO 2 ). If the samples were washed by acid and dried, potassium titanates could decompose to K 2 O and amorphous rutile. Based on the experimental results, a corrosion mechanism of Ti 3 AlC 2 in molten KOH was proposed.

“…They also measured many mechanical and electrical properties of the as-synthesized products [7]. By using the spark plasma sintering technique, Zhou et al [8] obtained high-purity Ti 2 AlC from the Al-excessive powder mixture of Ti:Al:C = 2:1.2:1 at 1100 • C and 30 MPa for 1 h. More recently, Lin et al [9][10][11] conducted a series of studies on the microstructural characterization, oxidation behavior, and corrosion resistance of Ti 2 AlC produced by the in situ hot pressing solid-liquid reaction process.…”

“…The chemical resistance of ternary carbides to some chemicals, i.e. NaOH, HCl and H 2 SO 4 (Jovic et al , 2006), Na 2 SO 4 (Lin et al , 2006a(Lin et al , , 2006bLiu et al , 2003a) and a eutectic K 2 CO 3 and Li 2 CO 3 mixture (Liu et al , 2003b), and the degradation of mechanical properties have been reported. Resistance to various hot corrosion attacks will therefore be identifi ed and studied.…”
