A subject of the invention is also a sacrificial anode for the protection of ship hulls constituted by a zinc-based alloy described above.

Los ejemplos de realización de aleación a base de zinc han sido objeto de mediciones de potencial de ánodo (en mV/ECS) y de capacidad (en Ah/kg) recordadas en la tabla siguiente, teniendo todas las aleaciones entre 0,10% y 0,20% de aluminio, y una cantidad de zinc suficiente para que el total de los porcentajes de los constituyentes sea 60 igual a 100%. Examples of realization of zinc-based alloy have been subject to measurements of anode potential (in mV / ECS) and capacity (in Ah / kg) remembered in the following table, with all alloys between 0.10% and 0.20% aluminum, and a sufficient amount of zinc so that the total percentages of the constituents is 60 equal to 100%.

El potencial de ánodo se mide con respecto a una referencia, que es el electrodo con calomel saturado o ECS. The anode potential is measured with respect to a reference, which is the electrode with saturated calomel or ECS.

Se desprende de estas mediciones que los potenciales de ánodo son parecidos y corresponden a unos valores 5 satisfactorios para una buena protección de los cascos de acero. It follows from these measurements that the anode potentials are similar and correspond to satisfactory values for good protection of steel hulls.

En lo que se refiere a la capacidad, ésta tiende a disminuir con el aumento del porcentaje de galio, y a aumentar ligeramente en presencia de indio. With regard to capacity, it tends to decrease with the increase in the percentage of gallium, and to increase slightly in the presence of indium.

Así, la presencia de galio, cuyo número atómico (31) es muy parecido al del zinc (30) aporta a la aleación a base de zinc las ventajas relacionadas con buenas prestaciones electroquímicas y con una protección eficaz del medioambiente debido a la ausencia de metales pesados. Thus, the presence of gallium, whose atomic number (31) is very similar to that of zinc (30) gives the zinc-based alloy the advantages related to good electrochemical performance and effective environmental protection due to the absence of metals heavy

La invención se ha descrito haciendo referencia a unos ejemplos de realización que corresponden a unos 15 porcentajes de galio dados a título ilustrativo y no limitativo y se extiende a los casos de los valores intermedios de estos porcentajes. The invention has been described with reference to some embodiments that correspond to about 15 percentages of gallium given by way of illustration and not limitation and extends to the cases of intermediate values of these percentages.
