Chemical analysis should be conducted on the original material to determine if the material was of proper type and grade, whether it met appropriate standards, and whether deviation from the specifications contributed to the fracture, wear, breaks corrosion and failure. Wet chemical analysis, Atomic Absorption, X-ray Photoelectron, Auger Electron and Secondary Ion Mass Spectroscopy are all potentially suitable methods of chemical analysis, depending on the particular need of the situation. The techniques differ in important ways. Other parts of the failure “system” may also require analysis, including corrosion products, coatings and liquids.
