The petrochemical, refining, and process industries are long overdue for new corrosion resistant coating technology. This study will provide an overview of silicon-based chemical vapor deposition (CVD) nanocoatings that, when applied to stainless steel and other alloys, fight corrosion while simultaneously easing design, fabrication, and integration of coated components.

By using a gas-phase CVD process, parts with complex geometries or narrow passageways such as valves and filters can be thoroughly treated both internally and externally. The coating is covalently bound to the base substrate to give durability and flexibility without flaking, while the thin profile (up to 1μm thickness) has no impact on design tolerances. Despite the submicron thickness, the silicon- based CVD coating offers advanced surface chemistry that is extremely inert, and effectively hinders corrosive interaction with the surface.

The coatings are tailored to provide additional unique properties that complement their corrosion resistance, including hydrophobicity, anti-fouling and carbon coking resistance. Silicon-based CVD coatings on stainless steel are cost-effective alternatives to super alloys in corrosive environments with HCl, sea water, and more. In this paper, the materials properties and corrosion performance of coated- stainless steel samples will be examined and compared to uncoated stainless steel controls.
