Component blank, has brake disk provided with plane upper surface section using forming procedure, where upper surface section is provided by deformation and provided with fine-grained structure for providing hardened upper surface
Component blank, has brake disk provided with plane upper surface section using forming procedure, where upper surface section is provided by deformation and provided with fine-grained structure for providing hardened upper surface
The blank (1') has a brake disk provided with a plane upper surface section using a forming procedure for manufacturing a surface hardened component. Masses (M') of deformation are provided on a part of an upper surface (10') of the blank and subjected for provision of a fine-grained structure in respect to non-transformed material. The surface section is provided by the deformation and provided with the fine-grained structure for providing a hardened upper surface. The surface section engages a circular-shaped or ring-shaped surface, where the blank is made of metal or metal alloy. Independent claims are also included for the following: (1) a method for manufacturing components by deformation of a component blank (2) a tool for forming a component blank (3) a device for forming a component blank.
