Investigations on the Oxidation Behavior of Max‐Phase Based Ti ₂ AlC Coatings on γ‐TiAl

Synthesis and characterization of Ti 2 AlC coatings by magnetron sputtering from three elemental targets and ex-situ annealing

“…The absence of a MAX phase and significant inter-diffusion between the coating and the substrate during annealing suggest that a diffusion barrier would be needed for synthesis of a MAX phase coating on Si or some metallic substrates [45].…”

Oxidation and Decomposition of Ti₂AlN MAX Phase Coating Deposited on Nickel-Based Super Alloy IN718

“…This unusual combination has attracted considerable attention worldwide and makes MAX phases a promising material for wear and high temperature applications. Primarily Ti-based MAX phases Ti 2 AlX have been synthesized using hot pressing and spark plasma sintering [4,5] as well as using several coating techniques such as DC-magnetron sputtering [6][7][8][9][10][11], pulsed magnetron sputtering [12], pulsed cathodic arc [13], pulse plasma hollow cathode nitriding [14], cold spray [15] HVOF [16,17] and air plasma spray [18]. The oxidation and corrosion behavior has taken a centre stage.…”

“…Several works described the oxidation behavior and oxidation mechanisms of Ti 2 AlX bulk material and coatings [19][20][21][22][23][24][25]. Moreover, the oxidation of MAX phase coatings deposited on metallic substrates has been studied in few works [26][27][28], but the outcome of the interaction between coating and substrate at high temperatures has not been extensively investigated. This issue is a main point, when MAX phase coating will be applied on component parts based on Ni super alloys in aerospace or gas turbines.…”
