Thermal treatment method for a micromechanical horological component derived from the LIGA method and exhibiting very low thermal inertia, said method including the step which consists in locally heating one area of the micromechanical horological component to increase hardness by local phase modification, the component being heated for a sufficiently short time that only the locally heated area is affected by the thermal treatment, the phase of the untreated portions of the component remaining unchanged. |
