“…This oxide has also been obtained by mechanochemical synthesis by grinding constituent oxides by Zhang [23]. The LaCrO 3 formation at high temperature on chromia forming alloys has been described by other authors [13,[24][25][26][27]. The present results indicate that the reaction between Cr 2 O 3 and La 2 O 3 occurs at the beginning of the oxidation process on all coated specimens.…”

“…Estas distintas nanoestructuras tienen excelente potencial para utilizarse como revestimientos de interconectores en celdas SOFC. Otra opción es recubrir estas aleaciones con una capa de óxido, que posteriormente reaccionaría con la cromia, formándose una cromita (o cromato), por ejemplo, recientemente, a través de una plantilla térmica de crecimiento tipo Cr 2 O 3 y esparcimiento de capas de La 2 O 3 , se ha demostrado la formación del revestimiento LaCrO 3 sobre la aleación SS-44 48 . Los resultados revelaron que las muestras con revestimiento, presentan resistencia eléctrica más baja comparada con las muestras no recubiertas, después de una similar exposición térmica en eléctrica; (5) los coeficientes de expansión térmica, deben ser compatibles con el sustrato de forma que, el revestimiento sea resistente a la fractura durante el ciclo térmico 7 .…”

“…The formation of iron substituted Mn(Cr,Fe) 2 O 4 instead of Cr 2 O 3 or MnCr 2 O 4 was found to improve the conductivity of oxidised interconnects [15] and to decrease the evaporation of chromium [16]. A second eventuality consists in modifying their surface by applying surface treatment, able to balance the two opposed properties: corrosion resistance and electrical conductivity [6,[17][18][19][20][21], by improving the oxide scale adherence, the resistance to thermal cycling and by decreasing the resistivity of the scale [11]. A previous study showed that it was possible to form perovskite compounds from reactive element oxide (REO) deposited by metal organic chemical vapor deposition (MOCVD) on chromia-forming steels [22].…”
