Innovative Advances in Coatings for Extreme Environmental Thermal Radiators and Complex Surfaces

This proposal fulfills the technology needs and provides the durable, stable thermal control material systems (TCMS) coatings that is Operator-sprayed with needed structural/adhesive tolerance to coating thickness variation and is dust shedding in charging environments and can furthermore survive and operate in the extreme environments. The recent efforts at AMSENG for the Lunar Applications indicated that the Charge Dissipating TCMS based on the secondary emission engineering are the promising concepts and have very low dust sticking ability to the lunar simulant dust. We propose extending this work towards coatings with newly designed required shelf life Binder concepts for the Cementatious Sols for the extreme environments with the requirements of the Operator-sprayed coatings with needed tolerance to coating thickness variation while meeting the thermal cycling vacuum environments and have the stable space optical, dissipative performance with accelerated, elevated cure schedules with innovative New Engineered Binder systems. Thus, the proposed efforts can address the feasibility evaluation of the advanced dust shedding TCMS coatings for the Lunar and Mars Extreme Environments through: • Process Newly Designed Cementatious Sols for the Shelf life with PZT™, BNNM™, Doped Zn/Mg:βAGO™ and Synthetic Low EOL Pigment Concepts for the passivated Y2O3 and Y2Ga5O12 • Process Selected Pigments with New Rad Hard Cementatious Sol concepts with Elevated Temperature Cure iterations. • Provide the Dust Shedding TCMS coatings concepts for Thermal Control for durable long life and harsh extreme environments • Evaluation and selection of low cost coating processing options, with feasibility proof through GEO simulation, and Dust Simulation • Qualify and recommend Validation efforts for the Reliable Material Systems and processing options for Lunar / Mars Mission hardware
