I need to remove the phosphatized top layer from certain parts of
crimping tools. Unfortunately the contact areas were treated with the
rest of the tool. The phosphatizing caused an increase in friction
beyond acceptable values which resulted in 100% failures during the
crimping. The problem is that the multi-part chains are connected by
(oiled) hinges and dust or sludge producing ways to remove it would
need a complete dismantling of the tools, which causes huge costs.
Is there any solvent/visuous substance or something that makes the
phosphatized layer swell that can be applied locally and removed with
something like a q-tip or be sucked away?
This prob is "too inorganic" for me ...thx a lot for any suggestions.
