“…This stress increases with the oxide growth (especially in the parabolic oxidation regime, in the first few hundred nm of the oxide scale). After exceeding the critical value, a phase transformation from tetragonal to monoclinic phase occurs [4]. The newly created phase is completely stable but porous and flaky, forming a non-protective oxide scale [1].…”

Los materiales refractarios son de gran importancia para la humanidad, debido a su capacidad de resistir altas temperaturas. Son empleados en la industria del cemento, cerámica, vidrio, metalúrgica, siderúrgica y petroquímica. La mayor preocupación a nivel industrial, es que los materiales refractarios son sometidos a varios mecanismos de desgaste durante el proceso de producción, tales como: ataque químico, mecánico, termomecánico y carga térmica. Si el material no cuenta con las propiedades adecuadas, su durabilidad se verá afectada, y por ende los costos de producción. En este sentido la combinación de los nanomateriales, se convierte en una importante alternativa para mejorar las propiedades de los materiales refractarios, proporcionándoles mejor densidad, baja porosidad, resistencia a la erosión, baja conductividad térmica, entre otras. El presente artículo realiza una revisión de varios trabajos de investigación, acerca de la evolución de los nanomateriales aplicados a los materiales refractarios, entre los que se mencionan el uso de grafeno, dióxido de titanio, óxido férrico, magnesia, zirconia, alúmina y sílice, para mejorar las propiedades físicas de los materiales refractarios. De manera general, los estudios demuestran que el uso de los nanomateriales, provee a los materiales refractarios mejores propiedades, en rangos de concentración específicos. Sin embargo, todos los estudios han sido realizados a nivel de laboratorio, por lo que sería promisorio su uso a nivel industrial.

“…To our knowledge, Raman imaging has been used more scarcely to understand Zircaloy corrosion, even if its use tends to emerge recently. [19][20][21][22] For different reasons, Zr corrosion layers are well suited to this type of analysis, providing their thicknesses are higher than a few micrometers. As a matter of fact, the analysis of cross-sectional metallographic preparations gives much more information than more usual analysis from the sample surface.…”

Successive technological improvements have made Raman imaging systems very efficient. Raman imaging applications now cover a wide range of scientific fields, including high-temperature materials corrosion, also known as dry corrosion. The analysis of the phenomena occurring during corrosion requires knowledge in metallurgy, thermodynamics, chemical kinetics, solid-state chemistry, and physics. Part of this information (crystallographic phases, stress state, oxygen transport, etc.) can be obtained, at least qualitatively, from the analysis of Raman images of the oxidation layer. Throughout this paper, we consider as a prototypal example the oxidation of a particular zirconium alloy, Zircaloy-4, used in the nuclear industry as cladding materials in light-water reactors. Through some examples, the aim of the present paper is to describe what kind of information this method can bring, to review its merits and weaknesses. The analysis protocols methods described herein are not exhaustive, but most probably represent a simple way to read and understand the Raman images. These few examples show that rather subtle details that concern phase distribution, strain, and oxygen transport can effectively be captured by this method. Most probably, Raman imaging may be applied to other alloys or systems as well.
