摘要
This invention relates to a method of inhibiting the cavitation-erosion corrosion of aluminum surfaces. The method comprises the step of contacting the aluminum surface with a formulation comprising a corrosion inhibitor composition comprising one or more carboxylic acids, or salts or isomers thereof, and a polymerizable-acid graft polymer which comprises an unsaturated grafting acid and an alkylene oxide polymer, or copolymers thereof. This method has been demonstrated to be a surprisingly effective means to inhibit cavitation-erosion corrosion of aluminum surfaces found in the cooling systems of internal combustion engines.
