  • Patent number: 11586145
    Abstract: A component intended to be in friction contact with another component, the component being coated with an electrically conductive layer in one piece, at least partially covering every surface of the component, the friction occurring on at least one of these surfaces, called the functional surface, the functional surface being surrounded by a plurality of side surfaces, the component having on its functional surface a texture formed of a succession of troughs coated with the electrically conductive layer, the troughs each extending between two side surfaces such that the electrically conductive layer remains in one piece over the component despite the wear caused by friction on the functional surface. The invention also relates to the method for manufacturing the component by the DRIE (deep reactive ion etching) process, wherein surface defects on the sides machined by the DRIE process are used to form the troughs.
