FRICTION MEMBER PROVIDED WITH LUMINESCENT MARKERS AND ASSOCIATED MANUFACTURING METHOD

Abstract

The invention relates to a friction member (1) of a braking device, said member being intended to be fixed on a vehicle wheel, said member having a friction surface (13) intended to come into contact with a friction lining of a movable component of the braking device, characterized in that said friction surface is covered with a first coating (11) comprising luminescent markers, and with a second coating (12) for protection against wear, superimposed on the first. The invention also relates to a method for manufacturing such a member. Figure [3]

Claims

8. Method for manufacturing a braking device disc, according to the preceding claim, characterized in that the luminescent markers are coordination polymers based on rare earths, preferably based on lanthanide, while the first coating (11) is preferably made of stainless steel.

9. Method of manufacturing a braking device disc, according to claim 7 or 8, characterized in that the second wear protection coating (12) is made of stainless steel loaded with carbides, preferably chosen from the list defined by titanium carbides, tungsten carbides, chromium carbides.

10. Method of manufacturing a braking device disc, according to any one of claims 7 to 9, characterized in that the first coating (11) is produced by thermal projection with a thickness of between 50 and 300 microns.
