Abstract The protective bronze film was prepared by mixing the reaction product of oligosaccharide (COS) and modified tannic acid (TA) with polyvinyl alcohol polyethylene glycol. Chloroacetic to carboxylate TA used generate sodium tannate. N,N’-Dicyclohexylcarbodiumide (DCC)/1-Hydroxybenzotriazole (HOBt) as a condensing agent form an amide bond between carboxylic amine COS-TA. synthesized chara...

the Sol–gel nanocomposite coatings have been investigated for copper metal as a potential replacement for the hazardous and banned hexavalent chromate conversion coatings. TiO2–CdO nanocomposite thin films were deposited on copper using the sol–gel method. The sol-gel coatings were prepared using a sol obtained by the hydrolysis and condensation of tetra-o-butyl titanate. They were doped with c...

Graphene oxide (GO), derived from the two-dimensional nanosheet graphene, has received unprecedented attention in field of metal corrosion protection owing to its excellent barrier performance and various active functional groups. In this review, mechanism “labyrinth effect” composite coatings against was demonstrated systematically. The origination, structure properties GO were also analyzed. ...

The inhibition of corrosion behaviour carbon steel in Well water has been studied by the anticorrosion natural Jeera dye (JD) and ZnSO4 system. Results Obtained Weight loss study shows 98% Maximum Inhibition efficiency at 10 ml Extract 50ppm ZnSO4. Synergistic parameters suggest that a synergistic effect existing between extract Zn2+.Statistical “F” test also revealed this effect. Surface analy...

Superhydrophobic films were fabricated on a titanium substrate with or without anodizing by using a self-assembling method. Firstly, the pretreatments of mechanical polishing/anodizing or mechanical polishing only were conducted, respectively. Subsequently, the preparation of polydopamine film layer, deposition of nano-silver particles, and post modification of 1H,1H,2H,2H-perfluorodecanethiol ...
