The process involves producing a controlled electrical discharge (spark) in an between the prepared flat surface of an aluminum specimen and a counter electrode.
For aluminum alloys, remains the most widely cited in material specifications (e.g., AMS, QQ-A, UNS). astm e125117a pdf
While the PDF is not free, it is an essential investment for any metallurgical laboratory conducting ISO 17025-accredited testing on aluminum and magnesium alloys.
