..., the failure occurred due to typical contact corrosion wherein the alloyed welding seam represented the less noble electrode. The martensitic structure may have contributed to the failure as well. Due to the typical nature of the failure, no recommendations were made. Pipe Recuperators Welded joints...

.... The galvanic series also allows one to determine which metal or alloy in a galvanic couple is more active. Metals that are more anodic in a given galvanic cell are prone to corrode by metal dissolution or electrochemical oxidation. The more cathodic material is more corrosion resistant (i.e., more noble...

... are produced in the thermal decomposition of PETN at 100 C. This was a very unusual corrosion problem in that a very noble metal, gold, was being corroded preferentially to a much more reactive alloy, the Pb-Sn-In solder.
