Development of Anti-corrosive Polyester Powder Coatings
… the environmentally unfriendly liquid paints for anti-corrosive purpose. In this study, UV-resistant polyester/TGIC powder coatings for outdoor application were developed instead of the widely used epoxy-based coatings. Three types of additives and functional filler, namely zinc phosphate with …

A review and development of accelerated test methods for anti-corrosive organic coatings
To enable improvements in the development of anti-corrosive coatings quick methods of evaluation are required and several are available which are both qualitative and quantitative. This investigation reviews both types of method, the first in the form of traditional salt spray exposure and the …

Modification of nanoparticle surfaces for emulsion stabilization and encapsulation of active molecules for anti-corrosive coatings
… particles have high barrier properties for corrosive species. The comparison of films containing silica-polystyrene composite particles with and without 8-hydroxyquinoline shows higher electrochemical impedances when the inhibitor is present in the film. By applying the Scanning Vibrating …

Effect of anti-corrosive coatings on the bond between corrosion-damaged rebar and concrete repair materials
Reinforcement corrosion is the largest contributor to the deterioration of existing RC structures worldwide. The aggressive electrochemical process causes destruction to the steel by a loss in cross section and rib height, which in turn affects the bond between steel and concrete and consequently …

Innovative Deposition of Corrosion Inhibitors by Abrasive Blasting
… process was investigated. A selection of anti-corrosive materials were mixed with garnet and tested in abrasive blasting. Material deposition was analysed by electron microscopy and the inhibition efficiencies of the treatment determined in electrochemical corrosion tests. It was found …

The tribological behavior of graphene and its role as a protective coating
… hypothesis. Graphene's potential as an anti-corrosive coating was demonstrated for macro-scale, commercially-available electrical connectors. It was demonstrated that even a monolayer of graphene can prevent oxide and reduce electrical contact resistance by orders of magnitude.

Investigation into corrosion protection by coatings using the electrochemical noise method
… the substrate. An important property of organic anti-corrosive coatings is the ability to protect the substrate at a break in the coating. In the scribed work the level of protection afforded at exposed metal by the coating was related to the Noise Resistance value. The third area of this …

Feasibility Study of a Natural Uranium Neutron Spallation Target using FLiBe as a Coolant
… were created from Hastelloy-N due to their anti-corrosive properties of molten salts such as FLiBe and their resistance to neutron damage. The final design chosen was a "Sandwich" design utilizing a section of thick plates followed by several smaller plates then finally a section of thick …

Investigations of Press Bonded Zinc-Rich Powder Coatings
Zinc-rich powder coatings (ZRPCs) are promising environmentally friendly alternatives to solvent-borne zinc-rich coatings. There are several difficulties and challenges with formulating and manufacturing these coatings. A novel technique without extrusion was assessed to avoid excessive wear of the …
