ChemInform Abstract: Chemically Vapor-Deposited Mo/Re Double-Layer Coating on Graphite at Elevated Temperatures.

Abstract Graphite and carbonaceous parts are being extensively employed in industrial and high-tech fields. Since these materials suffer from severe oxidation at elevated temperatures, it is vital to keep them safe from being damaged and corroded at high-temperature working conditions. In this study, a double-layer coating was prepared to achieve this aim. Primarily, SiC was coated on graphite samples via pack cementation method and then a layer of nano α-Al2O3 was coated on it through the electrophoretic deposition (EPD) method to improve the oxidation resistance at high temperatures. This alumina coating was further sintered only for 20 minutes at a relatively low sintering temperature of 1350 ºC in a microwave furnace to densify and close the oxygen permeation paths. Finally, this double-layer fabricated coating could reduce the weight loss by oxidation about 50 times in comparison with the bare graphite. Regarding the excellent oxidation protection performance of this double-layer coating and its feasibility for production scale-up, it can be further investigated to protect various carbon-based engineering materials from oxidation at high temperatures.

Layer Coating

In mass manufacturing of optical fibers, the wet-on-wet polymer resin coating is an efficient process for applying double layer coatings on the glass fiber. This paper presents an analytic study on the behavior of non-Newtonian polymer resins in the double layer coating liquid flow inside a secondary coating die of the optical fiber coating applicator. Based the approximations of fully developed laminar flow and the power law model of non-Newtonian fluid, the coating liquid flow of two immiscible resin layers is modeled for the simplified geometry of capillary annulus, where the surface of glass fiber moves at high fiber drawing speed. The effects of important parameters such as non-Newtonian fluid properties, the coating die size, and fiber drawing speed are investigated on the resin velocity profiles and secondary coating layer thickness.
