Cammett, “The Influence of Surface Enhancement by Low Plasticity Burnishing on the Corrosion Fatigue Performance

Corrosion fatigue, stress corrosion cracking and high cycle fatigue initiating from corrosion pits are primary failure mechanisms that reduce the structural integrity of aging aircraft. A chemically active environment, susceptible material and either static or alternating tensile stresses are required for failure. Conventional approaches to mitigate corrosion related failure mechanisms in aircraft usually involve isolation from the corrosive environment via protective coatings, alloy substitution or modifications in design to reduce stresses, all expensive solutions. This paper describes an alternate approach employing surface enhancement b
