is made possible owing to the softer material of the shaft 2 compared to the material of the component 3 in fig3 6 the roughness 7 for example the laser spots 20 are always introduced into the component 3 or cam 4 it of course also being conceivable for laser spots to be produced on the shaft 2 and thus borders 24 to be produced on the shaft 2 it being necessary for the shaft 2 to undergo carburisation first in order to be hardened during production of the laser spots carburisation can be omitted if the shaft 2 is manufactured from a carbon rich material such as c60e this has the advantage in particular that only a single component namely the shaft 2 has to be machined and not a multiplicity of components 3 or cams 4 in experiments a torque to turn could be increased from approx 135 to 225 nm if laser spots were produced on the shaft 2 and even to 325 nm if laser spots were produced on the component 3 which corresponds to an increase of over 100 torque to turn means the moment at which the component 3 on the shaft 2 begins to slip the laser structuring of the cam seat on the shaft and or cam side is a promising method for achieving considerable increases in the torque.
