“…The results of pure Co coatings after annealing at 800 C indicated that a Fe-rich layer between outermost layer and innermost layer. This is similar to previous result with SmCo coatings [37] Besides the expected oxides described above, silica (SiO 2 ) and alumina (Al 2 O 3 ) were also found at the scale/substrate interface, as reported in other work [38]. Although both SiO 2 and Al 2 O 3 have high resistance, the discontinuous distribution means there is unlikely to be a significant effect on the electrical resistance of interconnect.…”

“…9,17,18 The key requirements for a protective coating include dense structure, high electronic conductivity, thermal, mechanical and chemical compatibility with the adjacent components and low diffusion coefficients of Cr and O. Among coating mate-rials, such as reactive element oxides, 11,[19][20][21][22][23][24] nitrides, [25][26][27] conductive perovskites [28][29][30][31][32][33][34][35][36][37][38][39] and conductive spinels, 10,35,[40][41][42][43][44][45][46][47][48][49] Mn 1.5 Co 1.5 O 4 spinel has been actively investigated by many researchers for its excellent electrical conductivity, thermal expansion match with ferritic alloys and chromium retention capability. 41,42,[50][51][52][53][54][55] For fabrication of dense and well-adherent protective spinel coating layers, various deposition techniques have been investigated, including s...…”

“…Ambos resultados, sugieren que la PVD es un método eficaz en la fabricación de revestimientos de alta calidad para interconectores metálicos. Recientemente se han investigado otros revestimientos como los compuestos SmCoN y TiAlN (30 % y 50 % de Al) 43,44 . Ambos, demuestran ser estables a 700 ºC, lo cual es útil para inhibir la migración de Cr y Fe a partir del sustrato.…”
