Abstract
1324653 Activation and electroless plating UNITED KINGDOM ATOMIC ENERGY AUTHORITY 11 Dec 1970 [11 Dec 1969] 60626/ 69 Addition to 1247007 Heading C7F Prior to electroless plating , a substrate is bombarded with a dosage of ions sufficient to provide an activated, but not a coated surface, the ions being derived from a source forming a plasma of ions and electrons, and the surface being subjected to alternate periods of bombardment by said ions and electrons respectively in order to prevent build-up of charge on the surface. As shown, make-and-break contacts 1, one of C and the other of Pd, are driven by vibrator 2 and an arc is produced by D.C. source 3. A.C. is applied between 1 and extraction electrode 4 by winding 5, there being beyond the aperture in 4 two arcuate plates 6, one electrically connected to 4 and the other connected in phase to 5. Thus there are produced in +ve and -ve half cycles Pd ions and electrons respectively which are deflected to bombard substrate 7, any neutral particles being caught on plates 6. The ion energy may be 100-1000 eV, the substrate glass or plastics, and the subsequent electroless coating Ni or magnetic alloy, e.g. Ni-Co-P.
