Definitions
- the invention relates to a method for producing wear-resistant cylinder running surfaces of internal combustion engines which are created on cylinders or cylinder liners cast from alloyed, in particular also low-phosphorus, cast iron, by the method steps specified in the preamble of the main claim.
- This object is achieved according to the invention in a method with the method steps specified at the outset by a special execution of certain method steps, namely in that, by appropriate guiding of the laser beams relative to a cylinder bore wall, extending obliquely to the cylinder axis and including an acute angle of approximately 10 ° to 60 ° with the latter Hardness traces are generated with an edge distance X between two adjacent ones, which is so large that the maxima of the tensile stresses occurring in machine operation, which lie between them and at a distance K from the hardness edge, cannot coincide and thus the condition X is greater than 2 - K obeys .
