The effect of abrasive blasting on the fatigue and corrosin of an aluminium-copper alloy

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...
