ABSTRACT:
A method of surface treatment of a metallic base material, and particularly, a method of electroless plating in which the base material to be plated is immersed in an aqueous solution containing a water soluble metal salt, an acid component selected from the group consisting of gluconic acid, glucono delta lactone and a water soluble salt of gluconic acid, and a high concentration of a hydrolyzed carbohydrate. The high concentration of carbohydrate in combination with the gluconic acid component increases the throwing power of the plating bath to thereby reduce the time of immersion necessary to develop a given plate thickness.
