1 Fretting corrosion is primarily a surface damage phenomenon occurring as a result of small cyclic movements between two materials caused by cyclic loading. Fretting damage can occur in vacuum, although it then would be better to speak of fretting, rather than fretting corrosion.
Depending on the process conditions, corrosion by CO2 and H2S, chloride-induced localised pitting or crevice corrosion, stress corrosion cracking and/or H2S-induced sulphide stress cracking may be encountered by metallic materials used for wires, casings, tubing and piping in oil and gas field service.
