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 aluminum 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 in combination with a fluoride and/or a fluorocarboxylic acid or salt thereof. These compositions have been found to significantly improve the high temperature magnesium corrosion protection properties of coolants, and are of use in automobile engine coolant systems.
