Abstract RU 2227175 C2

FIELD: compositions used for protection of magnesium, magnesium- aluminum, aluminum-magnesium and aluminum alloys in cooling liquids of engines and liquid heat-transfer agents. SUBSTANCE: corrosion protection is effected due to selected group of aliphatic and aromatic carboxylic acids or salts of these acids and alkaline metals, ammonium or amines together with fluoride and/or fluorocarboxylic acid or its salts. EFFECT: improved high-temperature corrosion protective properties of cooling liquids for alloys containing magnesium. 16 cl, 1 dwg, 2 tbl, 6 ex
