    • Galvanic protection of steel is provided by means of coupling thereto of zinc binary alloys of Zn/8 to 18% wt. Co or Zn/20 to 50% wt. Mn with teachings of method of protection, the protected steel having the alloy coupled thereto, as well as the alloys per se. Also, a technique for determining alloys useful for the cathodic protection is taught with the technique including determining the critical cathodic protection potential for steel and the galvanic current and corrosion potential for candidate binary Zn alloy compositions followed by coupling to the steel of one such alloy composition whose determined corrosion potential is lower than the critical corrosion potential for the steel in the corrosive environment in which protection is sought.
    • 通过与Zn / 8〜18重量%的锌二元合金的结合来提供钢的电气保护。 Co或Zn / 20〜50% Mn与保护方法的教导,具有与其结合的合金的保护钢以及合金本身。 此外,用于确定用于阴极保护的合金的技术教导了包括确定钢的临界阴极保护电位和候选二元Zn合金组合物的电流和腐蚀电势的技术,然后与一种这样的合金组合物 其腐蚀电位低于腐蚀环境中钢的临界腐蚀电位。
