High-temperature corrosion presents significant challenges to wrought alloys. To resist such degradation, these alloys typically rely on the formation of a protective oxide scale. However, this oxide scale can deteriorate over time, eventually losing its protective function. From a commercial standpoint, it is essential to develop alloys that are viable for broad market adoption. This introduces additional challenges: an ideal alloy must not only be capable of forming a protective oxide scale but also of maintaining it under diverse environmental conditions. In certain industrial processes, such as ammonia cracking, the atmosphere contains extremely low oxygen levels, preventing the formation of an oxide scale. In such cases, the alloy must rely solely on its intrinsic composition for corrosion resistance. This talk will address some major challenges faced by wrought alloys—particularly Haynes Ni- and Co-based alloys—in resisting high-temperature corrosion phenomena such as oxidation, sulfidation, carburization/metal dusting, and nitridation. |
