Corrosion Preventive Compounds for Corrosion Prevention/Mitigation (Aermet 100 Steel)

Abstract

The role of corrosion preventive compound (CPC) in corrosion specifically general corrosion and a localized corrosion: stress corrosion cracking (SCC) and hydrogen embrittlement of AerMet 100 steel was investigated in 3.5% NaCi solution. Eighteen CPCs were evaluated for the effectiveness and persistency in corrosion prevention/mitigation, determining the essential parameters: open circuit potential, effective period, and threshold stress intensity for stress corrosion cracking (Kiscc). It was found that: (1) CPC ZC-OlO is most effective and persistent in prevention/mitigation of general corrosion, respectively, (2) Carwell AR500 and Omega 2775 are best in that of SCC, and (3) Break Free SMX is optimum in that of hydrogen embrittlement.
