Aluminum Composites With Small Nanoparticles Additions: Corrosion Resistance

Research of corrosion resistance of the aluminum powder composites containing microadditives (0.01 ? 0.15% is executed about.) zirconium oxide nanoparticles. Extreme dependence of speed of corrosion of aluminum composites in 10-% solutions of sulfuric and nitric acid from the maintenance of nanoadditives is shown. It has been shown the dynamics of mass loss of aluminum composites with nanoparticles of ZrO2 during corrosion tests in acids solutions. The lowest corrosion rate of 3.36 mm/a of nitric acid was observed in the sample containing ZrO2 0.01 vol.% nanoparticles. For the case of sulfuric acid with the best result of 2.21 mm/a showed the material with 0.05 vol.% nano-additive.
