Abstract: This article provides an insight into the nature of high temperature corrosion mechanisms that can prove detrimental to alloy performance when operating within aggressive environments, such as those within the power generation sector and other industrial environments. In order to understand high temperature corrosion, an initial understanding of alloy behavior in an oxidizing environment is required. Following this, key degradation and failure mechanisms have been discussed such as, sulfidation, type I and type II hot corrosion, fluxing methods and high temperature corrosion fatigue in metal alloys, primarily nickel-based superalloys for gas turbine engine application.
