Abstract
A method of controlling a continuous process of phosphating metal surfaces in which an acidic zinc phosphate solution is brought to the steady state and there maintained in response to conductivity change, as phosphating proceeds, by addition of replenishments (a) acidic zinc phosphate and (b) alkali metal ion in a definite ratio of addition rates. Preferably the zinc phosphate solution also comprises chlorate and optionally nitrate ions as depolarising oxidant. Preferably with ferrous metal surfaces is also added a rapid-acting oxidant to maintain ferrous ion at low concentration.
