At the present day chromium plated articles are saving the country many tons of badly needed metals. The beautiful, bright,luster that chromium has is no longer the prime quality that makes its use so extensive. Today its extreme hardness has taken the foremost place. Parts worn by use and re-claimed with chromium, not only wear longer than the original ones· but they also save valuable metal and time put into new ones. New articles plated with chromium have increased life, and thus the time and metal needed for replacement is greatly reduced.
The present chromium plating baths containing sulfuric acid as the active agent in electrolysis presents many problems leading to investigation and experimentation as far as the throwing power, plating range, and efficiency is concerned. Many addition agents have been tried with different degrees of success. The purpose of this investigation is to improve on the above factors and show that bright deposits can be obtained using an organic addition agent such as sodium benzenesulfonate
