A method of treating a tool (10) includes texturing at least a region (32) of at least one surface of the tool to increase surface roughness and friction resistance. The tool may be in a variety of forms such as a cutting tool insert. The texturing process may be carried out by any suitable method such as laser beam impacting, grinding, sandblasting, molding, chemical etching, photolithography, and/or reactive ion etching. Tools made by the method also are disclosed.

La présente invention concerne un procédé servant à traiter un outil (10) A cet effet, on texture au moins une région (32) d'au moins une surface de l'outil de façon à augmenter la rugosité superficielle et la résistance au frottement. L'outil peur se présenter sous diverses formes, et notamment sous celle d'une pastille d'outil de coupe. Le traitement de texturage peut se faire selon tout procédé approprié, et notamment l'attaque au faisceau laser, le meulage, le sablage, le moulage, l'attaque chimique, la photolithogravure, et/ou le mordançage par ions de réaction. L'invention concerne également des outils obtenus selon ce procédé.
