NO·RINSE PHOSPHAnNG PROCESS
DEVICE FOR ELECTROCHEMICAUY MACHINING RECESSES
US. Patent 5,976,272. Nov. 2, 1999 R. Seidel et al., assignors to Henkel, Duesseldorf, Germany
In a process for phosphating a surface of steel, zinc, aluminium, or their alloys by treatment with an acidic, zinc- and phosphatecontaining solution and drying the surface without rinsing, the improvement, which comprises contacting with a phosphating solution containing 2 to 25 gIL of zinc ions, 2 to 25 gIL of manga-
trolyte solution flows; means forming an inflow for the electrolyte solution; and means forming a return arranged so that the electrolyte solutions is conducted through the return opposite to a direction of the inflow between the disk and a component, said means for forming the return being formed as a channel.
