Abstract

By means of the mechanical alloying method (MA), Ti-Al coatings were deposited on Ti substrates. Then, as-synthesized coatings were treated by pulsed argon plasma with energy up to 185 J/cm². Irradiation of the Ti-Al MA-coating with pulsed argon plasma beams with energy density higher than 135 J/cm² resulted in melting of the near-surface layer that in turn initiated the liquid-phase reaction between Ti and Al to form the Al₃Ti compound. Melting led to smoothing of the coating structure. The coating microstructure and volume fraction of Al₃Ti phase was conditioned by plasma energy. The thickness of the modified layer was several microns. Phase composition of plasma-treated coatings depended on its element composition. The plasma treatment of the Ti-Al-Si-C and Ti-Al-W-C coatings with energy of 150 J/cm² led to formation of Ti₅Si₃ and TiC along with Al₃Ti compound.
