Abstract

Chromium is one of the hardest metals and when properly plated gives a beautiful lustre. It has a fine resistance to oxidizing agents and does not tarnish up to 600°C. Oxygen has little effect on chromium plate, making the latter invaluable for embellishments and decorative purposes.

However, there are difficulties to be overcome in chromium plating, such as,

  1. Poor throwing power.
  2. Formation of trivalent chromium.
  3. Evolution of hydrogen at the cathode.

It has been found that current efficiency is low, resulting in low throwing power, uneven plating and waste of electric energy.

In this thesis it will be attempted to obtain the region of best current efficiency as well as the conditions wherein the least hydrogen will be liberated.
