Abstract
A metal substrate provided with surface textures wherein different texture patterns are provided over predefined surface areas of the metal substrate and wherein the different texture patterns are tailored to predefined surface properties of a product which is to be made out of the metal substrate as well as to a method for applying such surface textures on the metal substrate.
Claims20
A metal substrate, provided with different texture patterns over the surface area of the metal substrate,
- wherein each said texture pattern comprises dimples which are recesses with
- a diameter in a range of 25-60 μm,
- a depth in a range of 2-6 μm and
- a density in a range of 180-600 dimples per square millimetre,
- wherein each said dimple in each texture pattern is spaced from each other said dimple to provide surface coverage of 30% to 80%;
- wherein the dimples respectively have a shape selected from the group consisting of round shape and oval shape;
- wherein the textures of said different texture patterns differ with respect to each other in at least one of diameter of the dimples, the depth of the dimples, number of dimples per surface area, positioning of the dimples, and spacing of the dimples with respect to each other.
