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 appropriately guiding the laser beams relative to a cylinder bore wall obliquely to the cylinder axis and including an acute angle with the latter, traces of hardness are generated, with a Edge distance X between two adjacent ones, which is so large that the maxima lying between and at a distance K from the hardness edge of the tensile stresses occurring in machine operation cannot coincide, and thus the condition X is greater than z. K obeys.
  • the cylinder running surfaces of cylinders or cylinder liners of internal combustion engines cast from alloyed, and in particular also low-phosphorus cast iron, can be made wear-resistant by the method steps described below.
  • Figures 1, 2 and 3 each show traces of hardness 1 with a width a in a known arrangement and assignment to each other. All of these three known arrangements have proven to be disadvantageous, as explained at the beginning. In the arrangement of the hardness traces shown in Fig. 1, these are spaced apart from one another, but not so far that the tensile residual stresses do not influence one another, i.e. could overlay. The edge distance b between two adjacent hardness marks 1 was therefore too small. In the other known arrangement shown in FIG. 2 with immediately adjacent hardness traces 1, the influencing of them is even greater than in the case of the embodiment according to FIG. 1, because their tensile residual stresses are in each case in the tempered, dashed and designated edge zones had layered even more.
  • hardness traces 4 are generated, which - as can be seen from FIG. 4 - run parallel to one another and at an angle to the cylinder axis 3 and enclose an acute angle ⁇ therewith.
  • This angle ⁇ will generally be in a range from approximately 10 ° to 60 °.
  • the hardness tracks 4 are spaced so far apart that there is an edge distance X between each two adjacent ones that is so large that the maxima of the machine operation occurring between and at a distance K from the hardness track edge Tensile stresses cannot coincide, and thus condition X is greater than 2.
  • K obey.
  • the width f of the hardness traces 4 which run obliquely to the cylinder axis 3 according to the invention is freely selectable and, depending on the application, can be adapted to the requirements.
  • the cylinder bore walls 2 are honed to the final diameter in order to maintain the cylinder running surfaces, and those material elevations are removed which had resulted during the hardening during the structural transformation into a martensitic structure.
  • the cylinder bore walls then have signs of hardness, preferably with a surface roughness of RZ 6 u + 3 and R 3Z 2 u to 4 u.
