Abstract
Ground surface comprising a substrate (110) having a Young's modulus of between 100 and 1000 GPa, and in which the ground surface has, on a working surface (120), a Vickers hardness of between 1300 and 10 000 kgf/mm2, and/or a surface coating forming the working surface, in which the surface coating contains amorphous carbon and/or titanium nitride and/or chromium nitride and/or tungsten carbide.
Claims19
A ground surface comprising:
- a substrate having a Young's modulus of between 100 and 1000 GPa, the substrate having a relief having a mean texture depth,
- wherein the ground surface has, on a working surface thereof, a Vickers hardness of between 1300 and 10,000 kgf/mm2, and
- wherein the mean texture depth is between 0.3 mm and 1.7 mm.
A ground surface comprising a substrate having a Young's modulus of between 100 and 1000 GPa and a surface coating formed directly on the substrate and defining a working surface,
- wherein the surface coating comprises amorphous carbon, titanium nitride, chromium nitride, tungsten carbide or any combination thereof, and
- wherein a mean texture depth of a relief of the substrate on the working surface is between 0.3 and 1.7 mm.
A method for manufacturing a ground surface, the method comprising:
- forming a relief having a mean texture depth in a surface of a substrate, the substrate having a Young's modulus of between 100 and 1000 GPa,
- wherein the ground surface has, on a working surface thereof, a Vickers hardness of between 1300 and 10,000 kgf/mm2, and
- wherein the mean texture depth is between 0.3 mm and 1.7.
