<p>Method for coating micromechanical components of a micromechanical system, in particular a watch movement, comprising: providing a substrate (4) component to be coated; providing said component with a first diamond coating (2) doped with boron; providing said component with a second diamond coating (3); wherein :said second diamond coating (3) is provided by CVD in a reaction chamber; during CVD deposition, during the last portion of the growth process, a controlled increase of the carbon content within the reaction chamber is provided, thereby providing an increase of the sp2/sp3 carbon (6) bonds up to an sp2 content substantially between 1% and 45%. Corresponding micromechanical components are also provided.</p> |
