Paper Title:
Processing and Properties of GPTMS-TEOS Hybrid Coatings on 5083 Aluminium Alloy
  Abstract

The hybrid nanocomposite coatings were processed in solution using acid-catalyzed hydrolysis and condensation of precursors 3-Glycidoxypropyl trimethoxysilane (GPTMS) and Tetraethoxysilane (TEOS) forming self assembled nanoscale composite. Coating were applied by dipping 5083 aluminium alloy in sol-gel solutions at several stages and different aging times. Effect of GPTMS-TEOS sol's aging time on thickness, adhesion, and corrosion behaviour of hybrid organic-inorganic GPTMS-TEOS sol-gel coatings have been investigated. The results indicated that thickness of hybrid coatings increased but adhesion decreased with increasing aging time. Adhesion test and electrochemical polarization behaviour reveal that if the coating process was chosen correctly, the coating had a good adhesion strength and corrosion resistance.
