Hewins, M.A.H. Institution Royal Aircraft Establishment RAE Date 1984-08-31 Abstract Rotating bending fatigue tests have established that glass bead and alumina grit blasting have only a slight effect on the fatigue properties of 2014-T6 aluminium alloy. Exposure to salt fog for 8 hours or alternate immersion in 3½% salt solution for 3 days reduces the fatigue strength from 170 MPa to 107 MPa and 64 MPa respectively but substantial improvements in fatigue strength may be achieved by abrasive blast cleaning to remove the 4t corrosion. Total immersion tests made in 3½% salt solution to examine the effects of abrasive blasting on corrosion have demonstrated that the corrosion rate and type of pitting attack on 2014-T6 aluminium alloy sheet are dependent on the abrasive used and on the amount of corrosion which has occurred prior to blast cleaning.
