...Abstract Aluminide coatings were produced by halide-activated pack cementation (HAPC) and halide-activated slurry cementation (HASC) on Ni-base superalloys (UNS N07208, UNS N06230, and UNS N07718). Both HAPC and HASC are in situ chemical vapor deposition processes activated by halide salts...

... by many other natural components of asphaltene, paraffin, or types of bitumen (highly viscous), etc. There are many different types of “oil” products and are classified based on their lack of miscibility with water. Abstract Coatings have the function of resistance to environmental attack, i.e. barrier...

...Specifically of high interest to corrosion technologists is the use of graphene and graphene oxide (GO) as barrier materials for preventing corrosion or even biocorrosion. Atomically thin layers of graphene can serve as a protective coating that inhibits corrosion of underlying metals...

...Abstract Corrosion resistance performance requirements of coatings varies across the wide range of markets. As an example, a coating technology developed for protecting aircraft aluminum alloys may not provide sufficient protection for steel assets such as bridges and large industrial parts...

...EXPERIMENTAL PROCEDURE Abstract The use of traditional corrosion inhibitors in paints and coatings continues to be challenged from both an environmental and performance aspect. End users are demanding better corrosion performance and in many formulations this cannot be achieved with traditional...
