Timepiece part, timepiece comprising same, method for manufacturing same, and surface treatment method

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. 本发明涉及一种表面处理方法，其用于由包含通过粉末冶金制造法或增材制造法获得的不规则结构的部件制造金属基和/或金属陶瓷基钟表部件，所述不规则结构为例如孔和/或析出物和/或条纹，该方法包括通过在部件的表面区上进行表面重熔来改善部件的表面光洁度的步骤。本发明还涉及一种用于制造钟表部件的方法，用于钟表的金属基和/或金属陶瓷基钟表部件，以及钟表。
