Abstract
Thermoplastic substrates, particularly those comprising polycarbonate, ABS or polycarbonate-ABS blends, are coated with an adherent aluminum coating having a thickness of at least about 1.5 microns by a process which includes fluorination of the surface followed by physical vapor deposition of aluminum. Fluorination is preferably effected by treatment with a plasma of a fluorine compound, especially a fluorocarbon such as carbon tetrafluoride.
