Estudo e caracterização das camadas de óxido de ferro puro.

Abstract

The oxidation process leads, in several cases to the degradation of the materials that are under an oxide layer produced. It can be affirmed, that the development of the oxide system depends on several factors: atmosphere oxidizer, mechanical properties of the oxide and of the metal and presence of tensions in the process When the oxide is a composed with several layers, the presence of a system with inter-relations physical-chemistries and mechanical is verified and more complex. That is the system found in several industrial processes or even when several materials, above all the metals and ferrous leagues, when the same ones are placed in use, resultant of the oxidation process. The knowledge of the influence of such processes individually and of the relationship of the group of remains the properties and morphology of the oxide layer, constituted of many layers, needs to be certain. It is treated of an element of significant importance for the understanding of the oxidation process of any systems receptive of degradation through referred phenomenon, that constitutes the essence of this work.
