MATERIAL-STEEL, ALUMINUM, BRONZE-COMBINED GALVANIC, STRESS CORROSION OF

Abstract

Tests were conducted to determine what effects the various dissimilar materials in the landing gear have on accelerated stress corrosion of the landing gear axle material, 4340 steel. Based on test results the following conclusions were made: water absorption by the various landing gear greases was virtually equal with a 200 to 300% increase over the amount present in the grease; and the combined galvanic effect of the dissimilar metals in the landing gear fail area does not increase stress corrosion of 260-292 KSI Ftu 4340 steel when tested in a 20% salt spray accelerated stress corrosion environment.
