Surfaces of two γ-TiAl alloys, Ti-47 at% Al-2at% Nb-2 at% Cr (MJ12) and Ti-47 at% Al-2 at% Nb-2 at% Mn + 0.8 at% TiB2 (MJ47), have been modified by acetylene plasma deposition at bias voltages of -4, -5 and -6 kV for 3.6 × 103 s (1 h) and 1.44 × 104 s (4 h). Knoop hardness (HK) of the alloys is incr...
