Project Title: Open Atmosphere In Situ Processing of Thermal Control Thin Films for Spacecraft

Technical Abstract (Limit 200 words)

Presently, quartz optical solar reflectors (OSRs) are used to provide desired absorbance and emissivity properties to the exteriors of satellites. While a reliable and proven solution, OSRs are expensive and application is limited to flat surfaces. One possible solution identified years ago was thin film depositions. It has been demonstrated that thin films generated by chemical vapor deposition can provide desired absorbance and emissive properties comparable to OSRs. However, traditional vapor deposition techniques require a costly high temperature reaction furnace and/or vacuum chamber limiting their widespread use for this application. With the capability to deposit inexpensively in the open atmosphere, the Combustion Chemical Vapor Deposition (CCVD) process has demonstrated the capability to deposit desired materials, such as Ag and SiO2, onto large and irregular surface areas. With a viable thin film deposition method, the weight reduction should be up to 80% versus OSRs. As a result, the CCVD technology offers a viable and compelling solution to address the needs of future spacecraft requirements.

Potential Commercial Applications (Limit 200 words)

Upon completion of the research contemplated in this Phase I, MCT will have developed a thin film oxide coating for use as a replacement for OSRs. Additionally, a prototype system will be designed for application of this coating using CCVD technology. In doing this, MCT will be uniquely positioned to capitalize on the $100M+ market for OSRs. With the current direction of industries headed environmental safety, CCVD can provide non-toxic processing, increased operational efficiency, and continuous coating onto large and irregular surface areas. Using Phase I and II award funding as support, the commercial objective of this proposal is to create a new, industry-wide standard process for environmentally safe production of these thin film coatings deposited via the CCVD process and then to place the process into commercial use as part of Phase III.
