"Development And corrosión behaviour (Electrochemical Polarization Method) of aluminium alloy (LM...

1. The electrochemical techniques used in this study They include linear polarizatio

1.1. Gathering Points

2. The experimental results of the polarization corrosion test done on different CNMMCs (containing 3, 6, 9 and 12 wt.% dispersoid content) and the resulting polarization curves obtained are shown in Figures 5 to 8, respectively

3. EXPERIMENTAL PROCEDURE

3.1. Nano- ZrO2 particles dispersed in Al alloy fabricated by stir casting technique, solidified under the influence of copper chill of 25 mm thick. The zize of the nano- ZrO2 particles dispersed varies from 100 to 200 nm

3.2. Microstructural characterization was conduced on polished CNMMC specimens using high magnification OLYMPUS metallographic microscope to investigate morphological characteristics of grain, reinforcement distribution and interfacial integrity between matrix and the reforcement

4. aluminum has good resistance to corrosion

4.1. Aluminum alloys are alloys derived from aluminum and other elements (usually copper, zinc, manganese, magnesium or silicon)

4.1.1. Zinc (Zn) Aumenta la resistencia a la corrosión

5. CORROSSION: deterioration of a material as a result of electrochemical etching by its environment

6. the combination of properties is its very low thermal conductivity and extremely robust. Also, some types of zirconia ceramics can lead oxygen ions. The components made of this material are significantly more expensive than components made of alumina ceramic
