Effect of nano TiO2 particles on the corrosion properties of an epoxy based coatings was investigated. Coatings and nano Titania were applied on standard phosphated steel panels by cathodic electrodeposition simultaneously. The coated panels were immerged in 3.5 NaCl solution for 2880 hours 120 days. The SEM and EIS technique were used to investigate the electrodeposion of nano Titania particle...

Based on silsesquioxanes (SSO) derived from the hydrolytic condensation of (γ-glycidyloxypropyl)trimethoxysilane (GPMS) and titanium tetrabutoxide (TTB), hybrid films on aluminum alloy (AA), film-GPMS-SSO (f-GS) and f-GS-TTBi% (f-GSTT5%–25%, i = 5, 10, 15, 20 and 25 wt%), were prepared and tested by electrochemical measurements with typical potentiodynamic polarization curves. The Icorr values ...

A novel multilayer coating containing bi-phase structures was designed via a magnetron sputtering method. Surface morphologies, structure and corrosion behavior of TaNbHfZr/CoCrNi have been investigated combination electrochemistry surface analysis. Such fcc CoCrNi amorphous TaNbHfZr layers exhibited an improved resistance compared with monolayer coating. The hardness elastic modulus the were s...

Reduction of calcium carbonate (CaCO3) scale formation on the equipment surface is essential in a wide variety industrial fields. In this work, polydopamine/polytetrafluoroethylene (PDA/PTFE) coating prepared by simple immersion stainless steel (SS) surfaces was developed to suppress CaCO3 adhesion. The PDA/PTFE-coated showed higher hydrophobicity (water contact angle = 133.50°) and lower free ...

Abstract Accidental damage on the diamond-like carbon (DLC) coating can have a great influence anticorrosion and tribological performances. In this study, DLC was deposited by DC unbalanced magnetron sputtering technique. The scratch tests with different loads of 2, 10, 20, 30, 40 50 N were used to imitate types accidental damage. surface states performance structures studied compared those wit...

Water-based anticorrosion resins have gone through many stages of evolution. Despite steady progress, there is still need for improvements. Recent innovations in the area of polymer colloids and hybrid materials offer new opportunities to develop novel coatings for metal protection. By choosing the appropriate technology, it is possible to design acrylic binders with improved barrier properties...
