A saltwater corrosion resistant hybrid composite is provided. The saltwater corrosion resistant hybrid composite coating includes at least one conductive polymer, crumb rubber, and a cured epoxy. The conductive polymer is dispersed in particles of the crumb rubber to form a network. The network is dispersed in the cured epoxy to form the saltwater corrosion resistant hybrid composite coating. A method of making of the saltwater corrosion resistant hybrid composite is also provided. A metal when coated with the resistant hybrid composite of the present disclosure is resistant to salt-water corrosion.

Composition for forming corrosion resistant composite coating

Saltwater corrosion resistant hybrid composite

The method of carbo-nitriding alumina surfaces is a process for applying a carbo-nitride coating to an alumina or alumina-based composite surface. The method involves the step of applying a phenolic resin to the alumina surface in a thin, uniform film. The resin-coated alumina surface is maintained in a controlled chamber at about 8 bar pressure at a temperature of about 175&#xb0; C. for about 2 hours. The surface is then heated at about 400&#xb0; C. for several hours in an argon atmosphere. This converts the phenolic resin to carbon. The carbon coated alumina surface is then scanned by a laser beam while applying nitrogen under pressure. The end result is the conversion of the alumina at the surface to aluminum carbo-nitride, the oxygen being released in the form of carbon dioxide.
