Resumen:
The objective of this work is the generation of a suitable surface, in microchannels of AISI 304 stainless steel for the manufacture of a microreactor, which ensures the anchoring of the active phase. The novelty of the work lies in achieving stabilization layer to work in different environments. The roughness generation was carried out by thermal treatment and passivation via alumina deposition by the impregnation method. The characterization was made with SEM?EDX and confocal microscope images. In a humid atmosphere, the generated surface showed high roughness with the presence of multiple filaments of iron oxide. Dilution of the suspension favoured the stability of the formed film.
