PCT No. PCT/EP93/00630 Sec. 371 Date Sep. 16, 1994 Sec. 102(e) Date Sep. 16, 1994 PCT Filed Mar. 17, 1993 PCT Pub. No. WO93/19218 PCT Pub. Date Sep. 30, 1993.In order to improve the adhesion of coatings, especially metal coatings, to the surfaces of plastic components, the latter are pretreated in low-pressure plasma with a process gas containing sulphur hexafluoride (SF6) which is substantially free of oxygen, the plastic surfaces being kept free of fluorine deposits or inclusions during the pretreatment.
