Abstract
Official abstract text for this publication.
A guiding member, having a body provided with a bore for mounting a mobile element is presented. The body consists of a metallic material. The bore has a surface layer treated against jamming over a diffusion depth of less than or equal to 0.6 mm. The surface layer has a hardness of greater than or equal to 500 Hv1 over a depth of between 5 and 50 μm.
First claim
Opening claim text (preview).
The invention claimed is: 1. A guiding member, comprising a body provided with a bore for mounting a mobile element, the body being made of a ferrous metallic material having a yield strength Re of between 200 and 600 MPa, characterised in that the bore has a surface layer treated against jamming over a diffusion depth less than or equal to 0.6 mm, the surface layer having a hardness greater than or equal to 500 Hv1 from a surface to a depth of between 5 and 50 μm. 2. The guiding member according to claim 1 , characterised in that the metallic material is chosen from structural steels or low-alloy steels. 3. The guiding member according to claim 1 , characterised in that the metallic material has a yield strength Re of between 300 and 600 MPa. 4. The guiding member according to claim 1 , characterised in that the metallic material has a yield strength Re of between 400 and 500 MPa. 5. The guiding member according to claim 1 , characterised in that the surface layer is treated against jamming over a diffusion depth of less than or equal to 0.3 mm. 6. The guiding member according to claim 1 , characterised in that the surface layer has a hardness greater than or equal to 500 Hv1 from a surface to a depth of between 25 and 50 μm. 7. The guiding member according to claim 1 , characterised in that the surface layer has a hardness greater than or equal to 550 Hv1 from a surface to a depth of between 5 and 50 μm. 8. The guiding member according to claim 1 , characterised in that the surface layer has a hardness greater than or equal to 550 Hv1 from a surface to a depth of between 25 and 50 μm. 9. A mechanical system, comprising a guiding member according to claim 1 , and a mobile element arranged in the bore of said guiding member. 10. A method for producing a guiding member according to claim 1 , characterised in that the method comprises the following successive steps: producing the body from a ferrous metallic material having a yield strength Re of between 200 and 600 MPa; carrying out a surface treatment of the bore in order to protect the guiding member against jamming, the surface treatment affecting a surface layer of the bore over a diffusion depth of less than or equal to 0.6 mm, the surface layer having, after the surface treatment, a hardness of greater than or equal to 550 Hv1 from a surface to a depth of between 5 and 50 μm.
