abstract = {Submicron Ti2AlC MAX phase powder was synthesized by molten
salt shielded synthesis (MS3) using a Ti:Al:C molar ratio of
2:1:0.9 at a process temperature of 1000°C for 5 hours. The
synthesized powder presented a mean particle size of ~0.9
µm and a purity of 91 wt. $\%$ Ti2AlC, containing 6 wt.
$\%$ Ti3AlC2. The Ti2AlC powder was sintered by pressureless
sintering, achieving a maximal relative density of $90\%,$
hence field‐assisted sintering technology/spark plasma
sintering was used to enhance densification. The
fine‐grained microstructure was preserved, and phase
purity of Ti2AlC was unaltered in the latter case, with a
relative density of $98.5\%.$ Oxidation was performed at
1200°C for 50 hours in static air of dense monolithic
Ti2AlC with different surface finish, (polished, ground and
sandblasted) which resulted in the formation of an approx. 8
µm thin aluminum oxide (Al2O3) layer decorated with
titanium dioxide (rutile, TiO2) colonies. Surface quality
had no influence on Al2O3 scale thickness, but the amount
and size of TiO2 crystals increased with surface roughness.
A phenomenon of rumpling of the thermally grown oxide (TGO)
was observed and a model to estimate the extent of
deformation is proposed.},
