Tidewater and Weather-exposure Tests on Metals Used in Aircraft
A 1939 technical report from the NASA Technical Reports Server, issued for aeronautical engineers and metallurgists, documenting tidewater and weather exposure tests of metals used in aircraft. Its plates are grids of photographed metal panels, showing corrosion and rivet behaviour after months or a year of exposure, with the test conditions and rivet types printed as captions. A designer could take from them the look of weathered, pitted metal, with rust halos and encrusted surfaces around rivet heads.
