PROTECTIVE COATING

摘要

FIELD: aircraft engineering.SUBSTANCE: this coating is composed by aluminium foil covering spacecraft components. Foil outer side has aluminium oxide ply, at least 30 mcm thick, applied by micro-arc oxidation thereon. Said aluminium foil is either mechanically secured to protected components or glued thereto. Tests and calculations show that said coating ensures active life of spacecraft for over 15 years.EFFECT: longer life under effects of spacecraft engine plasma effects.3 tbl
