This thesis considers a nanotechnology approach based on the production of metals pre-treatments and organic coatings (a complete protection system at all) designed from the nanoscale. The final aim is to develop protection systems with improved corrosion protection properties and a low environmental impact. In particular, multifunctional silane hybrid molecules were used to design sol-gel pre-...

Cathodic electrodeposition (CED) was used to coat the cast magnesium alloy Mg-9Al-1Zn-xRE with aluminum powder and epoxy. Immersion salt spray tests (ASTM B117) at room temperature for a total of 240 hours have been performed assess corrosion performances AZ91D alloy. At each 24-hour interval, samples were checked any damage or deterioration coating surface morphology. The X-ray diffraction (XR...

The intumescent retardant coating was fabricated by a combination of epoxy binder and flame-retardant ingredients for the steel plate. This paper investigates influence nanoclay content on improving fire properties fire-retardant coatings. performances coatings were determined test at 950oC one hour. degradation characterized Thermal gravimetric analysis (TGA). morphology, composition char stud...

Water at the interface is often the main cause of corro. sion, blistering, and disbandment of organic coating/substrate systems. Consequently, the transport of water from the environment to the coating/substrate interface is the subject of great interest in many industries such as organic coatings, asphalt pavements, and electronic packaging. There is no suitable method available to measure the...

Two hybrid sol-gel coatings, one acrylate-based and the other epoxy-based, were synthesized deposited on two cast aluminum-silicon alloys, Al-Si9-Cu3 Al-Si7-Mg0.3. Field immersion testing was performed in Adriatic Sea lasted 8 months. Coatings characterized before after terms of morphology, structure, composition, electrochemical properties artificial seawater. The level biofouling documented, ...
