Title
(EN) PROFILED SCREENING ELEMENT
(FR) ELEMENT DE BLINDAGE PROFILE
Abstract
(EN) Screening element in the form of a monolithic sintered member which has an external face and an opposite internal face, the surface of the faces being greater than 100 cm2 and the mean thickness Em between the faces being greater than 4 mm, the member being characterised in that at least a portion of the external face is textured so that Ai decreases from the internal face from a value of i greater than at least 50, A75 ≥ 0.2 × A0 and A95 < 0.9 × A0, 0.03 × A0 < A95 < 0.5 × A0 and A100 < 0.1 × A0, Ai being the area occupied only by the material in a plane i with an internal section with respect to the intermediate thickness Ei and i corresponding, as a percentage, to the fraction of the mean thickness Em in the plane i.
(FR) Elément de blindage sous forme d'un corps monolithique fritté présentant une face extérieure et une face intérieure opposée dont la surface desdites faces est supérieure à 100 cm2 et l'épaisseur moyenne Em entre lesdites faces est supérieure à 4 mm, ledit corps étant caractérisé en ce que sur au moins une portion de ladite face extérieure est texturée de telle façon que Ai décroit partant de la face intérieure à partir d'une valeur de i supérieure à au moins 50, A75 ≥ 0,2 × A0 et A95 < 0,9 × A0, 0,03 × A0 < A95 < 0,5 × A0 et A100 < 0,1 × A0. Ai étant l'aire occupée par le seul matériau selon un plan i de section interne à l'épaisseur intermédiaire Ei et i correspondant en pourcentage à la fraction de ladite épaisseur moyenne Em au plan i.
