The protection of duralumin from corrosion
A 1927 technical memorandum from the NASA Technical Reports Server, issued as a report on protecting duralumin aluminium alloy from corrosion, written for aeronautical engineers and metallurgists. Its single picture is a close photograph of corrosion attack on an aircraft sheet metal panel, showing pitted, streaked, grid-patterned metal surfaces with riveted seams, useful to a designer for raw industrial texture, weathered metal surfaces, and abstract patterns of rivet lines and panel edges.
