Abstract (en)
[origin: WO2022058159A1] Disclosed is a micromechanical component, in particular a timepiece wheel, in particular an escapement wheel, comprising a substrate with a first material comprising at least nickel and phosphorus, which substrate is covered, on at least one surface of the wheel substrate, by a coating of a second material comprising at least nickel and poorer in phosphorus than the first material, or devoid of phosphorus, and the second material constitutes the peripheral layer of the wheel at this at least one surface of the substrate.
