CORROSION INHIBITORS AND SYNERGISTIC INHIBITOR COMBINATIONS FOR THE PROTECTION OF LIGHT METALS IN HEAT-TRANSFER FLUIDS AND ENGINE COOLANTS |
摘要 |
Corrosion protection of magnesium and aluminium alloys in engine coolants and heat-exchange fluids is achieved by the use of a select group of aliphatic and aromatic carboxylate acids or the alkaline metal, ammonium or amine salts thereof. The addition of a fluoride and/or a fluorocarboxylic acid or salt thereof have been found to significantly improve the high temperature magnesium corrosion protection properties. |
