Conclusions

  1. 1.

    In systems composed of gallium and an oxide material, oxygen constitutes an adhesion-active substance, which substantially increases the strength with which the metal adheres to the substrate wetted by it.

  2. 2.

    Spontaneous spreading of gallium over oxide materials in the presence of oxygen is prevented by the presence of a strong oxide film on the surface of the melt.

  3. 3.

    In systems in which the oxide film on the wetting melt does not react with the substrate material, the presence of oxygen brings about no increase in adhesion strength.
