The footprint of surface modification treatments on the corrosion-fatigue of AA7075-T651

The footprint of surface modification treatments on the corrosion-fatigue of AA7075-T651

Different manufacturing and surface modification treatments distinctively affect the surface characteristics and microstructure of the workpiece, having a different impact on their effective life-span. The corrosion-fatigue behavior of as-machined (wire-EDM), blasted and anodized aluminum alloy 7075...
