The Effect of Adding CeO Nanoparticles to Cu-Ni-Al Alloy for High Temperatures Applications.

This work presents the effect of CeO nanoparticles (CeO-NPs) on Cu-50Ni-5Al alloys on morphological, microstructural, degradation, and electrochemical behavior at high temperatures. The samples obtained by mechanical alloying and spark plasma sintering were exposed to a molten eutectic mixture of LiCO-KCO for 504 h. The degradation of the materials was analyzed using gravimetry measurements and electrochemical impedance spectroscopy.

Effect of Atmospheric Corrosion on the Mechanical Properties of SAE 1020 Structural Steel.

Resistance to atmospheric corrosion in different environments located in Chile and the corrosion's effect on the mechanical properties of SAE 1020 steel were studied. Atmospheric corrosivity categories at each station under study were determined. These categories were C2, for Laja; C3 and C4, for the Arica and Antarctic stations, respectively; and the most aggressive, C5 and higher at Quintero.
