Abstract A method for measuring the spark-shower radiance of metals
when abraded on an abrasive grinding wheel was developed for
evaluating their sparking tendency. One hundred metals were tested
and rated relative to commercially pure iron. The radiance was
measured in units of energy per solid angle per area of the detector.
The metals tested included elemental metals, iron binary and ternary
alloys, iron-carbon ternary alloys, commercial steels, nonferrous
alloys, and a few hard-metal compounds. Some alloys were synthesized,
others were obtained commercially. Alloys which possessed
good strength properties were emphasized for selection. The results
indicate that the spark-shower radiance of plain carbon steels and
carbon alloy steels was greater than for pure iron. Certain elements,
particularly vanadium and chromium, reduced the sparking tendency of iron. Stainless steels and particularly nickel alloys displayed low
spark-shower radiance. Some metallic elements had much lower
radiance than iron, others much greater. Plain-carbon steels, heat
treated to a variety of hardnesses, gave radiance values which gen
erally increased with increasing carbon content and hardness, but
showed a decreasing radiance trend at high levels of carbon and
hardness.
