electro．deposition rate of chromium coating from a chromic sulfateelectrolyte were studied using Hull cell and quadrate cell．Theresults showed that the addition of auxiliary complexingagent is helpful for improving the quality and brightness ofdeposit，but remarkably decreases the coating thickness andplating rate．The electrodeposition of仃ivalent chromiummay be affected by the type and dosage of auxiliarycomplexing agent．A wholly bright deposit was obtained byaddin9 0．4 mol／L glycine as
