Abstract
The invention relates to a one-piece metal component including an electroformed metal body, the external surface of the body including, only over or to a predetermined depth, less trapped hydrogen than the rest of the electroformed metal body causing a hardening relative to the rest of the body in order to improve the wear resistance of the one-piece component while preserving a relative magnetic permeability of less than 10 and the ability to be driven or pressed fit.
Claims17
A one-piece component including an electroformed metal body comprising trapped hydrogen, wherein an external surface of the body includes, only to a predetermined depth, a depletion of trapped hydrogen causing a hardening relative to the rest of the body in order to improve the wear resistance of the one-piece component while preserving a relative magnetic permeability of less than 10 and the ability to be driven.
A method for fabricating a one-piece component comprising the following steps:
- a) forming a mould on an electrically conductive substrate;
- b) filling the mould by electroforming to form at least one one-piece metal component;
- c) releasing the at least one one-piece metal component from the electrically conductive substrate and from the mould;
- wherein the method further includes the step of:
- d) effecting desorption of the trapped hydrogen in the at least one one-piece metal component during electroforming so as to form, only over a predetermined depth of the external surface of the body, a hardening relative to the rest of the body.
