(FR) REVÊTEMENTS DE NICKEL À NANOCRISTAL MACLÉ DE TYPE MONOCRISTALLIN À HAUTE RÉSISTANCE ET LEURS PROCÉDÉS DE FABRICATION
Abstract
(EN)
A high-strength coatings and methods of fabrication yield single-crystal-like nickel containing nanotwins and stacking faults are disclosed. By using two steps having sputtering and electrochemically depositing Ni on (111) orientation copper, the single-crystal-like nickel having the nanotwins is manufactured for reducing corrosion of grain boudaries in a nanotwinned material.

L'invention concerne des revêtements à haute résistance et des procédés de fabrication permettant d'obtenir du nickel de type monocristallin contenant des nanocristaux maclés et des défauts d'empilement. En utilisant deux étapes comprenant la pulvérisation et le dépôt électrochimique de Ni sur (111) du cuivre d'orientation, le nickel de type monocristallin ayant les nanocristaux maclés est fabriqué de façon à réduire la corrosion des joints de grain dans un matériau à nanocristaux maclés.
