MATERIAL - STEEL SANDWICH PANELS - SILVER. COPPER.LITHIUM.BRAZED - CORROSION INHIBITOR FOR DEVELOPMENT OF,
Abstract
Ag-Cu-Li brazed 17-7 PH stainless steel test panels were exposed to 650 F air for one week and then treated in triplicate with ten different test corrosion inhibitors. These panels and uninhibited controls were then exposed for six weeks at the specified humidity. At the conclusion of the test, potassium chromate, sodiummetasilicate and phosphoric acid showed promise as inhibitors. Phosphoric acid was especially effective and eliminated virtually all corrosion. Since phosphoric acid is an active mineral acid, additional tests were conducted to determine the effects of removing the excess acid. It was shown that rinsing or neutralization treatment of the phosphoric acid inhibited panels prior to drying at 650 F removes the inhibitive effect. (Author)
