Anyone know what that was all about? Mr. "Motor Mouth", the civilian crew-chief at Edwards AFB, told me once, but can't remember anymore. Old Chief Lynn From some of the papers I found, I would suspect that it was a test panel to measure the corrosion resistance of a magnesium / Thorium alloy skin for high-speed aircraft with coatings Found several reports on tests by Convair dated 1957-1959 & 1962 "Dow #17 treatment applied to HK-31 magnesium-thorium alloy* protects the surface of the alloy against corrosion and at the same time offers a potentially good surface for adhesive bonding. Therefore, the purpose of this test request was to obtain information applicable to the adhesive bonding of Dow #17 treated HK-31 magnesium-thorium alloy" "I. Effect of Certain Process Variables on Dow #17 Treated HK-31 Magnesium-Thorium Bonded With AF-31 Adhesive" "II. Lap Shear Strength of Standard Dow #17 Treated Magnesium Thorium Alloy - Primed With EC-1459 and Bonded with AF-31 Adhesive " also a test report of a magnesium / Thorium alloy skin on a F9F and since Thorium is naturally radioactive , the warning.symbol... |
