51317--9542-Silicon-Based CVD Nanocoatings for Corrosion Resistance and Advanced Surface Properties

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.

Faced with growing demand to increase performance and lower costs the petrochemical and refining industry is long overdue for new corrosion resistant coating technology that is more easily integrated into production. This paper will discuss silicon-based chemical vapor deposition (CVD) nanocoatings that when applied to stainless steel and other alloys are proven to cut maintenance costs by offering corrosion protection equivalent to exotic metals while also easing design fabrication and installation of coated parts.By using a gas-phase CVD process components with complex geometries or narrow passageways such as valves and filters can be thoroughly treated both internally and externally. The coating is molecularly bound to the base substrate giving durability and flexibility without flaking while the thin profile (approximately 1µm thickness) has no impact on design tolerances. The silicon-based CVD coating’s performance is not directly related to thickness; rather itsadvanced surface chemistry is extremely inert greatly hindering corrosive interaction with the surface.Thecoatings are tailored to provide specific high performance properties that complement their corrosion resistance including hydrophobicity oxidation protectionabove 1000° C and coking/fouling resistance. The coatings’ versatility makes them ideal solutions throughout the refinery not to mention exploration and upstream applications. Silicon-based CVD coatings on stainless steel are cost-effective alternatives to super alloys that offer a myriad of additional benefits for boosting refinery output while decreasing maintenance-related costs. Here the silicon-based CVD coatings' material properties and corrosion performance will be examined and compared to alternative solutions.

Key words: nanocoating, silicon, chemical vapor deposition, CVD, coating, corrosion resistant, stainless steel, hydrochloric acid, sulfuric acid, H2S, hydrophobic
