In order to meet the industry requirements, the ability to achieve good mechanical properties under a wide variety of conditions should be considered. A major advantage of adhesive bonding over conventional mechanical fastening such as bolts and rivets is that it enables dissimilar materials to be joined. However, these materials (i.e. cured epoxy resins) are brittle and have poor resistance to cracks which indicate low capability to absorb the external energy therefore limiting their application in fields requiring high adhesive and impact strength. The incorporation of secondary components or modifiers into the epoxy system can overcome these issues. Sol-gel technology is finding increasing applications, for example, as hydrophobic selfcleaning and decorative colour coatings, formation of low-temperature cure high ...

Under the aggressive environment, corrosion leads to the formation of corrosion products. The use of inhibitor substance is considered as one way to protect the metal surface against corrosion. The inhibitor is chemically adsorbed py the surface of the metal and forms a protective thin film with inhibitor effect. The protection can also be achieved by a combination of inhibitor ions and metallic surface. The current work was evaluated using corrosion inhabitation of carbon steel in NaCl solution by carbimazole\Zn system. The ability of carbomazole as a good corrosion inhibitor is enhanced by the presence of Zn+2 when the concentration of carbomazole increased and this may be attributed to the protective film formed on the metal surface was withstand the continuous attack of corrosive ions. Also, the formation of complex Fe-carbomizole/Zn+2 linkages on the anodic sites of the ...
