Application:- providing adhesion strength to frictional compositions and general mechanical rubber goods;- preventing from carburization in cementation;- ensuring screwing ability in steel and cast-iron goods at higher temperatures;- sublayering of multilayer electroplatingDescription:- Electrochemical copper plating is obtained from weak electrolyte which contains citrate ions as a complexing agent. The operating density of electrolysis current is 1.0-2.2 A/dm2 in the stationary mode, that of pulse current being up to 10 A/dm2. The current yield makes up not less than 96-96%.- The developed technology enables making lustrous copper deposition directly onto steel and cast-iron surfaces without preliminary finishing. At the same time it ensures strong surface adhesion and prevents copper cementation on steel and cast iron.Advantages:- high deposition rates;- high throwing power - 70-80%;- no porosity with thickness being 3 um;- environmental safety of the electrolyte as it contains no cyanides or ethylene diamine.
Application: manufacture of semi-finished products (bands, strands) and moulded articles from thermo-plastic polymers, reinforced by continuous fibres.
