Abstract
A method of gluing a metal part to another part for use in a personal care device such as an electric toothbrush. The method includes steps of providing a metal, such as steel, part, and another, metal, part; treating a surface portion of the metal part with ultra-fast laser pulses having a pulse length in the femtosecond range, e.g., from about 1 femtosecond to about 990 femtoseconds, so that a surface layer of the metal surface is removed; applying an adhesive to the treated surface of the metal part or to a surface of the other part; and gluing the metal part and the other part together.
