Abstract
Surface Modification Processes for Use in LEO, GEO and Planetary Environments
Highlights
Among the major problems encountered by polymer materials, paints, graphite and polymerbased composites in LEO and GEO space environments one can mention erosion of materials in LEO due to the atomic oxygen effects, change in such functional characteristics like thermal optical properties, surface charging and space equipment performance degradation of highvoltage solar arrays due to arcing in GEO and secondary arcs on solar generators and a number of other problems in long-term modern antennae performance in GEO
An extensive review on surface modification technologies developed for protection of materials from the space environment and for impairing to them new functional properties in different space environments was published in 2010 [3]
Surface modification technologies present a viable alternative for protection and impairment of new functional properties to polymers, paints and other carbon-based materials and structures used in space
Summary
Among the major problems encountered by polymer materials, paints, graphite and polymerbased composites in LEO and GEO space environments one can mention erosion of materials in LEO due to the atomic oxygen effects, change in such functional characteristics like thermal optical properties, surface charging and space equipment performance degradation of highvoltage solar arrays due to arcing in GEO and secondary arcs on solar generators and a number of other problems in long-term modern antennae performance in GEO. An extensive review on surface modification technologies developed for protection of materials from the space environment and for impairing to them new functional properties in different space environments was published in 2010 [3]. Work on surface modification technologies that were developed at ITL either to protect the basic properties of the materials [4 – 11] or to change them in a desirable way, without altering the bulk properties [12 – 14]
