Abstract

Le procédé de texturation d'une surface sollicitée en frottement lubrifié (10, 11, 12), comprend une étape de projection de particules provoquant une déformation plastique de la surface durant l'impact, dans laquelle : Les particules projetées ont un indice de sphéricité moyen compris entre 0,80 et 0,90, et préférablement sensiblement égal à 0,86, Les particules projetées ont un diamètre inférieur à 200 microns, L'angle d'incidence alpha des particules sur la surface est compris entre 15° et 90°. La surface sollicitée en frottement lubrifié et texturée selon ledit procédé, présente des cratères de forme ellipsoïdale, répartis de façon aléatoire mais homogène.The method of texturing a surface subjected to lubricated friction (10, 11, 12), comprises a step of projection of particles causing plastic deformation of the surface during impact, in which: The particles projected have a sphericity index mean between 0.80 and 0.90, and preferably substantially equal to 0.86, The projected particles have a diameter less than 200 microns, The angle of incidence alpha of the particles on the surface is between 15 ° and 90 °. The lubricated and textured frictionally stressed surface according to said process has craters of ellipsoidal shape, distributed randomly but homogeneously.
