Descripción
The metallic coating of zinc alloyed with other metals such as nickel, has very good corrosion resistance. It was found that the type and quantity of particles, increases the hardness and the nickel content in the alloy at all current densities. Photomicrographs were made in electronic and optical microscope (in samples with particle, cross sectional views). We have found that there is an optimum thickness of 10 microns in which the intensity of texture in the material is increased. In this thickness in ZnNi - Al2O3, the Charge Transference Resistance, RTC in ohm, measured by Impedance was RTC ZnNi + Al2O3 > RTC ZnNi and in the Polarization Curves the corrosion current density is decreased. In salt spray tests on samples with the same thickness, it was found that the area with white rust is lower for Zn Ni with Al2O3 on the affected area that in other cases.
