Susceptibility of rare-earth-magnesium alloys to micro-galvanic corrosion

Síntesis, caracterización y evaluación de recubrimientos híbridos porosos sol-gel dopados con acetato de cerio sobre la aleación de magnesio WE54-AE

“…1(b). Dichas inclusiones, son específicamente precipitados de itrio, zirconio y tierras raras (RE, RareEarths) de composición Mg 14 YNd 2 [5], [20].…”

“…Por esta razón, dichas aleaciones encuentran principal aplicación en la industria del transporte en la fabricación de piezas de responsabilidad moderada, como partes de los chasis de automóviles, fuselajes de trenes, tranvías, aviones, etc. [5]- [7].…”

Cellular response to rare earth mixtures (La and Gd) as components of degradable Mg alloys for medical applications

“…[ [28][29] Consequently, the surrounding cells will be exposed to dissimilar amounts of RE ions, according to their location.…”

Biodegradation of Secondary Phase Particles in Magnesium Alloys: A Critical Review

“…It has also been reported that in zirconium containing magnesium alloys, zirconium-rich regions in the microstructure exhibited higher corrosion resistance than the zirconium depleted regions 20) . Coy et al 21) found that zirconium-rich precipitates exhibit a volta potential of 170 mV noble to that of the magnesium matrix, which they attributed to the presence of impurities such as iron, nickel and silicon in the zirconium-phase intermetallics.…”
