## Description

- description: In recent years, titanium alloys have been increasingly applied in
    the aerospace industry due to their low density, excellent mechanical properties,
    and corrosion resistance. Compared with bolting and welding, adhesive bonding
    offers advantages including reduced weight and more uniform stress distribution.
    In this work, a simple surface-activation method, namely electric-furnace heating
    at 200–800 °C for 1 h was evaluated to improve the adhesive bonding of ground
    Ti–6Al–4V sheets. Heat treatment produced a TiO2-rich surface, reduced adventitious
    carbon, and increased wettability. The optimum condition was 400 °C for 1 h, which
    yielded the highest energy release rate (Gc) of 1455 J/m2 in double cantilever
    beam (DCB) tests, with a predominantly cohesive failure mode (96 %). This was
    markedly higher than that of the as-ground surface, which exhibited a Gc of 924
    J/m2 and a cohesive failure proportion of only 46 %. At 800 °C, a thick Al2O3-containing
    layer formed and early delamination occurred at the brittle oxide/Ti–6Al–4V interface,
    driving Gc toward zero. After the treatment, the surface became recontaminated
    when the sheets were exposed to laboratory air above 48 h, resulting in hydrophobic
    recovery and a reduction in Gc. The comprehensive results indicate that an effective
    condition for Ti–6Al–4V is 400–600 °C for ∼1 h in air, followed by immediate bonding
    before any recontamination.
