Abstract (en)
[origin: WO2015155435A1] The invention relates to a method for treating a surface of a friction member comprising an organic matrix containing at least one inorganic material, such as a friction member of a clutch friction device (10). At least one area of said surface, referred to as the area to be treated (27), is treated by scanning it with a LASER beam along at least one predetermined path (25). The LASER beam has an energy density between 0.05 and 1 J/cm2, a frequency between 10 Hz and 10 kHz and a pulse duration between 1 ps and 1 ns.
