Preventing fouling (also known as coking or simply "sticking") on the surfaces of combustion and fuel delivery components is highly desirable as a way to improve efficiency, increase longevity, and ultimately reduce costs of surface, air, and undersea systems. Functionalized silicon-based CVD (chemical vapor-deposited) coatings are growing in interest as they prove to enhance the performance of mission-critical parts in challenging exposure environments. These coatings substantially increase the hydrophobicity, oleophobicity, and oxidation resistance of stainless steel, titanium, and other alloyed surfaces, even at high temperatures. Fuel injectors, heat exchangers, turbochargers, and other components have been proven to benefit from the CVD technology. The CVD coating process is performed in the gas phase which allows for uniform treatment of complex geometry parts like fuel injectors which are otherwise unfeasible to coat with traditional methods. This poster will introduce CVD coating technology and data illustrating the performance of the functionalized silicon-based surface treatments.
