摘要

Se presenta un estudio metalográficos de dos armas prerromanas afectadas por un proceso de cremación. Las armasrnposeen un recubrimiento exterior de magnetita que las confieren unas altas propiedades de protección frente a la corrosión. Esta capa es extraordinariamente tenaz y posee un espesor muy homogéneo, indicando que son producto de un proceso de fabricación intencionado más que una formación accidental durante los varios ciclos de calentamiento/enfriamiento que hg,n_sufrido los objetos. Hasta la fecha, la producción intencional de este tipo de recubrimientos ha sido atribuida a un proceso de soldadura de tres láminas metálicas diferentes. En este trabajo se propone un modelo alternativo de formación, el cual permite una simulación en el laboratorio en la que se forma exclusivamente una capa de magnetita.%A metallographic study of two pre-roman Iberian arms, affected by a cremation process, revealed the presence of an outer magnetite layer, providing highly protective properties. This layer is extraordinarily tenacious and of very homogeneous thickness, indicating an intentional manufacturing process rather than an accidental formation during the severe heating/cooling cycles the artefact suffered. Up to date, the intentional production of these types of layers has been attributed to a welding process of three different metallic sheets, here an alternative model is proposed, allowing, as could be simulated in the laboratory, the virtually exclusive formation of a magnetite coating.
