Abstract
The invention relates to a differential shaft (1) composed of a substrate having at least one flat surface (20) and comprising a coating layer deposited on the substrate. According to the invention, the machining of the flat surface (20) defines edges (21) bordering a bearing surface (11) of the substrate, and the edges (21) have a rounding having a radius greater than or equal to 0.05 mm.

A differential shaft composed of a substrate having at least one machining of a flat surface and comprising a coating layer deposited on the substrate, wherein the machining of the flat surface defines edges bordering a bearing surface of the substrate, and the edges have a rounding having a radius greater than or equal to 0.05 mm
A method for producing a differential shaft, comprising the following steps:
- obtaining a cylindrical substrate;
- machining a flat surface;
- depositing a coating layer on the substrate;
- wherein said method comprises a step of grooving an edge defined by the machining of the flat surface, prior to the depositing step.
