Abstract : Effort was made to evaluate the Delta TitaniumCadmium plating process with respect to its operating characteristics and ability to reduce or eliminate hydrogen embrittlement problems inherent with electroplated high strength steels. In addition to this, the corrosion resistance of the Delta titanium-cadmium plate was evaluated and compared to cadmium plate from a standard cadmium cyanide bath. The results of the evaluation of the operating characteristics of the new bath showed that it had a 100% anode efficiency and a mean cathode efficiency of 94.6% over a current density range of 20 to 30 amperes per square foot. Hydrogen embrittlement evaluation utilizing static fatigue notch tensile specimens showed that embrittlement did occur in high strength (300 KSI) steel, however, this could be relieved to some extent by baking the specimens at 375F for 24 hours. The corrosion tests were inconclusive. (Author)
