Definitions

  • the method according to the invention is intended for the treatment of all workpieces which are at least temporarily exposed to any sliding processes. These are in particular gear parts, bearings and the like, but also, for example, objects used for fastening, such as bolts, screw threads and the like. However, the greatest importance of the process lies in its application for the preparation of workpieces for cold forming.
  • Cleaned sheets of pure titanium (JIS grade 1) with the dimensions 100 ⁇ 50 ⁇ 0.8 mm were electrolytically phosphated with a phosphating solution of the following quality: 9.6 g / l zinc 36.3 g / l phosphoric acid (calculated as PO4) 2 g / l nitric acid 0.5 g / l sulfuric acid 0.03 g / l nickel pH approx. 3.0.
