The invention discloses a high-wear-resistance and high-corrosion-resistance high-manganese aluminum bronze alloy propeller and a manufacturing method thereof. According to the formula of propeller blades, each propeller blade comprises the following components of, in percentage by weight, 15% of manganese, 10% of aluminum, 5% of iron, 3% of nickel, 0.05% of boron, 0.05%-0.20% of other elements and the balance copper and inevitable impurities; and the other elements comprise one or more of strontium, zirconium, scandium and titanium. The manufacturing method comprises the steps of propeller blade preparation, titanium plating corrosion prevention, external electrode adding and the like, an external power source is connected with an external graphene electrode to form a communicating electric distribution path, when the propeller works, seawater serves as a communication medium, the seawater is decomposed into chlorine-containing substances through current, the corrosion resistance of the propeller is improved, and the service life of the propeller is prolonged. The propeller is simple in structure, only a zinc coating, an external electrode and a power source are additionally arranged, the corrosion resistance effect of the propeller is remarkable, and good practicability is achieved.

    本发明公开一种高耐磨耐腐蚀的高锰铝青铜合金螺旋桨及其制作方法,该螺旋桨叶片的配方及各自的重量百分比为成分按重量百分比为:锰15%、铝10%、铁5%、镍3%、硼0.05%,其他元素0.05~0.20%,余量为铜和不可避免的杂质;所述其他元素包括锶、锆、钪、钛中的一种或几种。其制作方法包括螺旋桨叶片的制备、镀钛防腐、加设外接电极等步骤通过外接电源接通外接的石墨烯电极形成一个连通的电流通路,在螺旋桨工作时,将海水作为连通介质,通过电流分解成含氯物质,提升螺旋桨的耐腐蚀性及使用寿命。本发明螺旋桨构造简单,仅加设镀锌层和外接电极和电源,但其耐腐蚀性能效果显著,具有良好的实用性。
