Abstract (en)

[origin: EP1655092A1] An electrolytic treatment method for a component having at least two through-holes (7, 7', 7'', 7''', 7'''', 7''''') involves treating (specifically coating) the interior surfaces (8, 8', 8'', 8''', 8'''', 8''''') of the holes using separate pole electrodes (19, 19', 19'', 19'''), having the same polarity. An independent claim is included for a component with at least two through-holes produced by the process.
