Abstract
The influence of sulfur content on notch sensitivity and hardness of electrodeposited nickel was determined. Charpy impact tests showed that deposits containing greater than 170 ppm of S were highly notch sensitive. Hardness was shown to be a direct function of S content; therefore, a rough approximation of S in deposits can be obtained from hardness measurements. Other techniques for identification of S (namely, wet chemistry, azide-iodine spot test, sodium-nitrate etch, and heating at 980 °C for 30 min) are discussed.
