Abstract
An adherent, smooth electrodeposit of chromium is produced on a nodular cast iron substrate from a chromium plating bath. The desired deposit is provided herein by activating the substrate, subjecting the activated substrate to an ultrasonic treatment, and thereafter plating chromium from a chromium plating bath. The method is particularly effective for electrodeposition of chromium on such substrates from commercial high energy efficient chromium electroplating baths, where ordinarily only roughened deposits are obtained.
