Abstract

L'invention concerne un objet (10, 110) pourvu d'une structure superficielle (14) permettant une meilleure adhérence d'un revêtement (12). La structure superficielle (14) présente des éléments de liaison (16, 160) et des rainures (18a, b ; 180), lesquels sont disposés en rang. Un élément de liaison présente une surface de recouvrement (20, 200), laquelle est inclinée dans une seule direction. Les surfaces de recouvrement (20, 200) des éléments de liaison (16, 160) sont inclinées dans la même direction, et ce dans la direction de la rangée (R). Un élément de liaison (16, 160) comprend en outre une première surface (24), laquelle est orientée dans la direction de la rangée (R), et une deuxième surface (32), laquelle est orientée dans la direction opposée à la direction de la rangée (R). La première surface (24) et la deuxième surface (32) sont transversales à la direction de la rangée (R). La réalisation des éléments de liaison (16, 160) et des rainures (18a, b ; 180) permet d'obtenir une possibilité de remplissage très satisfaisante de la structure superficielle (14) par le matériau de revêtement et la structure superficielle (14) confère au revêtement (12, 120) une adhérence très satisfaisante. L'invention concerne en outre un moule (50) selon l'invention permettant de fabriquer une structure superficielle (14) et un procédé de fabrication.
