Abstract
15-180g/l lead carbonate is added to a bath of borofluoric acid, together with a tin electrode and the electrolysis is carried out at 1-4A/1. After dissoln. glue is added to the bath, electrolysis continues with lead-tin anodes till the deposit on the cathode is less than 18% of the final thickness, then the following is added (g/l): 0.025-0.2 perfluor-octyl sulphonic acid, 1.25-40 ethylene-diamine-tetraacetate, 0.025-4 perfluoroethylcyclohexyl-sulp honic acid, 12-300 polytetra-fluoroethylene of 0.5-70 micron grain size. The coated item is immersed in this electrolyte, rinsed, and dried
