Abstract
Qualitative spectrographic analyses of metallic areas of less than 0.05 mm in diameter can be obtained by means of the equipment and methods described. The apparatus consists of (1) a device for holding a counter electrode and the specimen to be analyzed, (2) an electronic spark generator, and (3) a medium quartz spectrograph. Minute areas such as inclusions, segregations, crystalline phases, surface contaminations, metallic platings, and the extent of metallic diffusion have been successfully analyzed.Keywords
