Análisis de la microrugosidad mediante técnicas portátiles: aplicaciones y casos de estudio en patrimonio

espanolLa superficie de los materiales constituye la interfase entre los agentes de deterioro y el elemento patrimonial. La determinacion de la rugosidad tiene una amplia aplicacion en el campo de las ciencias del patrimonio, desde como inciden los procesos de deterioro en la superficie de los materiales, hasta poder establecer la idoneidad de tratamientos de conservacion, tanto en los tratamientos de limpieza del bien cultural como en las tecnicas de consolidacion y proteccion de sus superficies. Existen diferentes tecnicas para determinar la rugosidad de los materiales, pero muchas de ellas se realizan en el laboratorio y por tanto es necesario trasladar el bien patrimonial, lo cual no siempre es posible. El rugosimetro portatil es una tecnica no destructiva que permite determinar las caracteristicas de la superficie de un objeto a escala micrometrica y con representacion tridimensional. Se van a mostrar diferentes aplicaciones de esta tecnica en el campo de la caracterizacion y conservacion de materiales patrimoniales. EnglishThe materials surface is the interface between the decay agents and the heritage element. The determination of roughness can have a wide variety of applications in the field of heritage science, from how the deterioration processes affect the materials surface, to the determination of the suitability of conservation treatments, both considering cleaning methods applied to the heritage asset, as well as consolidation and protection techniques of their surfaces. There are several techniques to determine materials roughness, but many of them must be performed in the laboratory and therefore it is necessary to move the heritage element to there, which it is not always possible.

The portable roughness meter is a non destructive technique that allows the determination of the surface characteristics of an object at a micrometric scale and with a three-dimensional representation. Different applications of this technique in the field of heritage materials characterization and conservation are shown.
