Beschreibung
Zusammenfassung:	FIELD: machine building, power machine building electrical and radio engineering, more particularly chemical treatment of metal surfaces. SUBSTANCE: solution comprises, g/l: zinc ions (Zn ), 0.8-8.7; calcium ions((Ca2+)), 0.76-9.0; phosphate ions (in terms of HNO3(NO-@3)), 1.6-19.5; oxidizer P2O5), 3.6-31.5; potassium hydrofluoride waste containing at least 75% main substance, 0.048-0.615; and not more than 2 l of the water, the balance. The solution makes it possible to increase adhesion and corrosion resistance of coating in combination with paint coating. EFFECT: improved properties of the solution. 3 ex, 1 tblh
