Influence du brossage sur la réactivité des surfaces métalliques
Influence of brushing on the reactivity of metallic surface
Ecole Nationale Supérieure d’Arts et Métiers, Paris
Using a number of examples, the authors show it is possible to modify the reactivity of a metallic surface through varying the conditions of brushing of the metal. The parameters to be modified are: nature of the bristle, its diameter, its length, the brushing speed, the number of passes, the speed of each pass, etc. The surfaces thus brushed are then tested in an appropriate medium in order to bring out the variations in the surface reactivity. Besides, it is shown that these reactivity variations are not linked to roughness variations. Finally, it appears that through appropriate handling of the brushing parameters, several types of surfaces can be obtained: “ground” surfaces, “cold-hammered” surfaces or "machined" surfaces.
