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 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.
Pour protéger contre la corrosion des alliages de magnésium et d'aluminium en contact avec des liquides de refroidissement pour moteurs et des liquides d'évacuation de la chaleur, on utilise un groupe d'acides de carboxylate aliphatiques et aromatiques, ou bien le métal alcalin ou ses sels ammonium ou amine, en combinaison avec un fluorure ou un acide ou un sel fluorocarboxylique de ce fluorure. Ces compositions, dont il est apparu qu'elles permettaient d'améliorer notablement les propriétés anti-corrosion à haute température à l'égard du magnésium, conviennent donc pour les circuits de refroidissement des moteurs d'automobile.
