Embodiment Construction

[0023] The invention is based on a first option, consisting in the use of powder metallurgy or additive manufacturing techniques as a first step in the manufacturing method of watch components. This option has the first advantage of allowing complex and diverse shapes to be formed, including, for example, shapes not achievable by traditional metallurgical methods. On the other hand, this first option also has a second advantage, allowing the use of a wide variety of materials, even alloys or combinations of elements not obtainable by another conventional method, such as certain metal alloys that are not compatible with conventional metallurgy . Therefore, this first option according to the invention makes it possible to partly respond to the object of the invention.

[0024] However, these selected technologies have the particular characteristic of forming porous and often heterogeneous parts with visible surface defects, such as visible or perceptible irregularities such as ...

Abstract

The invention relates to a surface treatment method for manufacturing a metal-based and / or cermet-based timepiece part from a part comprising irregular structures obtained by a powder metallurgy manufacturing method or an additive manufacturing method. The irregular structures are, for example, pores and / or precipitates and / or stripes. The method includes the step of improving the surface finish of the part by surface remelting on a surface region of the part. The invention also relates to a method for producing a timepiece part, a metal-based and / or cermet-based timepiece part for a timepiece, and a timepiece.

Description

technical field [0001] The invention relates to a timepiece component for a timepiece and a method of manufacture for such a component. The invention also relates to a surface treatment method used in a method of manufacturing such a component. The invention also relates to a timepiece comprising such a timepiece component. Background technique [0002] In the watchmaking industry, the manufacture of components, especially for watch decoration functions, is subject to many constraints. First, due to its intended functionality, the part must obey certain mechanical constraints. In addition, the components must achieve an impeccable aesthetic appearance. Finally, it is often desirable to provide a timepiece component of a specific, often complex shape, in order to achieve a new overall aesthetic effect and / or efficiently satisfy a specific functionality. Furthermore, it is always preferable to propose a solution that allows the manufacture of such timepiece components in a...
