Definitions

  • the first thin layer 11, the intermediate layer 12 and the second thin layer 13 are deposited so that the watchmaking wheel set 10 formed comprises, in the sense and the direction of growth of deposition of said layers, a phosphorus concentration gradient defined for example by a progressive growth through the first thin layer 11, a stable state through the intermediate layer 12 and a progressive decrease through the second layer thin 13.
