Implication

This method demonstrates significant corrosion resistance in aluminium alloys, highlighting long-term protection in marine environments.

Key Points

  • The STZ coating achieved a static contact angle of 156°, indicating strong superhydrophobic properties.
  • Electrochemical tests showed a corrosion current density three orders of magnitude lower than the untreated substrate.
  • The multi-step approach involved chemical etching, hydrothermal deposition, and stearic acid modification.
  • After extensive abrasion, the coating retained 70% of its hydrophobic properties, indicating durability.
