• Description:
  The Bureau of Mines is studying methods of identification of scrap that will lead to better segregation, conservation of strategic materials, and better utilization of existing resources. Spark testing--the visual examination of the spark stream generated when a metal is struck against a grinding wheel--has been used successfully for many years in the classification of alloy steels. Research using spectrophotometric methods to determine the characteristics of the light emitted by the sparks, and a minicomputer to recall and compare spark patterns is described. The utility of this instrumental method for the rapid identification of stainless steels and superalloys is discussed. [Description provided by NIOSH]
