  • Patent number: 9683595
    Abstract: A metallic locking washer is configured to be mounted in a screw/nut system to engage between a nut and a bearing element. The metallic locking washer has a contact face suitable for coming into contact with one or the other of the nut and the bearing element. The contact face has a surface that is suitable for being brought along in friction against one or the other of the nut and the bearing element when the nut loosens. The contact face is coated, by thermal projection of an additive material, with a rough coating forming a rough surface, which increases the friction forces between the contact face of the metallic washer and one or the other of the nut and the bearing element.
