Abstract

PURPOSE: To economically manufacture the title sheet with satisfactory surface properties and chemical treatability without requiring an additional process by carrying out zinc electroplating with a plating soln. contg. a specific amt. of sulfate ions and a Ba salt.
CONSTITUTION: Zinc electroplating is carried out with a plating soln. contg. 10W 200 g/l of sulfate ions and 0.5 W 1000 ppm as Ba of a Ba salt. An adequate amt. of BaSO4 suspends in the soln. in the form of colloid, and Pb is adsorbed on or precipitated with the colloid, so Pb in the soln. is prevented from mixing into a plated film to manufacture a zinc electroplated steel sheet with superior heat resistance. The plating soln. may be a sulfuric acid bath or a sulfate ion-contg. mixed salt bath. The Ba salt includes Ba(OH)2, BaCl2 and BaSO4 previously made colloidal.
