Resumo |
Two amorphous ribbons with the compositions of Al<sub>88</sub>Ni<sub>6</sub>La<sub>6</sub> and Al<sub>86</sub>Ni<sub>6</sub>La<sub>6</sub>Cu<sub>2 </sub>were made using the meltspun method, and their thermal response and electrochemical behavior were studied comparatively. Differential scanning calorimetry (DSC) and electrochemical polarization measurements indicated that Al<sub>86</sub>Ni<sub>6</sub>La<sub>6</sub>Cu<sub>2</sub> exhibited slightly higher crystallization temperature (T<sub>x</sub>), lower melting point (T<sub>1</sub>) and better corrosion resistance in 0.01 mol · L<sup>−1</sup> NaCl alkaline solution. These results demonstrated that Cu (2%) addition could slightly promote the glass forming ability, but it could greatly improve the corrosion resistance of Al<sub>88</sub>Ni<sub>6</sub>La<sub>6 </sub>alloy in 0.01 mol · L<sup>−1</sup> NaCl alkaline solution.<br /> |
