Abstract In tires, cords consist of brass coated wires. Even if they are embedded in rubber matrix, wires remain sensitive to corrosion. This work proposes an evaluation of the electrochemical reactivity of the constituents of the wire: the steel, the brass, and the brass coated steel. Tests were immersed in solutions where pH, solution convection, and oxidizing species were controlled. Results confirm the establishment of galvanic coupling between iron and brass. In aerated and neutral solution, the dissolve dioxygen reduction acts on the interfacial pH modifying the reactivity of the brass coated steel.

表面和环境条件对黄铜、钢和黄铜涂层钢丝和黄铜涂层钢丝帘线腐蚀行为的重要性

摘要 在轮胎中，帘线由黄铜涂层线组成。即使它们嵌入橡胶基质中，电线仍然对腐蚀敏感。这项工作提出了对线材成分的电化学反应性的评估：钢、黄铜和黄铜涂层钢。将测试浸入控制 pH、溶液对流和氧化物质的溶液中。结果证实了铁和黄铜之间的电流耦合的建立。在充气和中性溶液中，溶解双氧还原作用于界面 pH 值，从而改变黄铜涂层钢的反应性。
