The space suit contains metallic bearings at the wrist, neck, and waist, which are exposed to the space environment. There is a need to maintain a high degree of insulation on the surface of the metallic bearings. Current methods to preserve the insulation feature include the use of anodized coatings and polyimide films. However, they are easily damaged and are hard to replace or repair. Innovations are needed to provide a protection method that is easy to maintain. Working with a developer and supplier of systems to NASA, we propose to demonstrate the feasibility of a self-healing insulative polymer coating on the metallic parts that will allow the coating to repair damages under normal operational conditions of the spacesuit. The self-healing capability is afforded through a novel polymer morphology. In Phase I, we will coat 17-4 PH stainless steel flat panels, test coating properties, and evaluate the self-healing performance under near ambient temperatures. In Phase II, the self-healing coating will be applied on a prototype metallic bearing and the coating composition and morphology will be optimized so that it meets all the functional performance requirements. A functioning prototype metallic bearing will be delivered to NASA. The goal is to achieve TRL 6 by the end of the Phase II program.
