摘要：
本发明揭示了一种抗海洋腐蚀耐用金属件，包括表层的第一抗蚀防腐层和内层的第二抗蚀防腐层，所述第二抗蚀防腐层包裹设置在所述第一抗蚀防腐层外表面，所述第一抗蚀防腐层由铜、锌、铝以及铅组成，各成分所占重量份数分别为：所述铜占55‑64份，所述锌占32‑39份，所述铝占11‑18份，所述铅占4‑11份，所述第二抗蚀防腐层由铜、锌、镍以及锡组成，各成分所占重量份数分别为：所述铜占48‑57份，所述锌占30‑38份，所述镍占7‑14份，所述锡占3‑10份。本发明具有耐磨性好、机械强度高、抗腐蚀性好、耐候性好、使用寿命长的特点。
摘要（英）：

The invention discloses a marine-corrosion-resistant durable metal component which comprises first anticorrosion layers and second anticorrosion layers. The first anticorrosion layers are surface layers, the second anticorrosion layers are inner layers and wrap the outer surfaces of the first anticorrosion layers, the first anticorrosion layers comprise, by weight, 55-64 parts copper, 32-39 partsof zinc, 11-18 parts of aluminum and 4-11 parts of lead, and the second anticorrosion layers comprise, by weight, 48-57 parts of copper, 30-38 parts of zinc, 7-14 parts of nickel and 3-10 parts of tin. The marine-corrosion-resistant durable metal component has the advantages of good abrasion resistance, corrosion resistance and weather resistance, high mechanical strength and long service life.
