Wettability inversion of aluminum-magnesium alloy surfaces

The paper presents the experimental results on use of low-temperature heating to reduce time wetting inversion (from superhydrophilicity hydrophobicity) aluminum-magnesium alloy surfaces textured by laser radiation. Stable growth contact angle 137.3–144.2° after (wettability properties deteriorate) was recorded. Wetting from hydrophobicity occurs in 2–3 hours samples. wettability depends type texture. A significant increase carbon content elemental composition near-surface layer samples their registered.
