    • A fatigue crack growth retardant material for application to aluminum and alloys thereof utilizes certain organic nitrogen compounds and an elastomeric polymer compatible herewith with respect to the curing properties thereof as well as the ultimate properties of the material and capable of stabilizing the nitrogen compound so as to inhibit the evaporation thereof to the atmosphere. The material inhibits corrosion of and retards crack growth in aluminum and alloys thereof when applied thereto. The material has particular utility when applied to the surfaces of structural parts of aircraft and is utilized as a protective coating as well as a sealant, dependent upon the amount of solvent added to the polymeric elastomer.
    • 用于铝及其合金的疲劳裂纹增长阻燃材料利用某些有机氮化合物和与其固化性质相容的弹性体聚合物以及该材料的最终性能并且能稳定氮化合物,以便 抑制其向大气中的蒸发。 当施加到其上时,该材料抑制铝及其合金中的腐蚀和延缓裂纹扩展。 该材料在应用于飞行器的结构部件的表面时具有特别的用途,并且根据添加到聚合物弹性体中的溶剂的量被用作保护涂层以及密封剂。
