This Research The Electroplating Method of Chromium was Used on iron ore (steel).
We studied the effect of addition of urea (NH2)2C=O] capable of complex formation with chromium ion (Cr+3) with the formate on the coating layer specifications. Study the correlation ratio between chromium ion and urea content in a manner that changes pH.
