Definitions

  • the inner and outer sleeves can be made from inexpensive metal, for example steel.
  • the housing must be substantially sufficiently heat-resistant and have the required mechanical strength.
  • Particularly preferred manufacturing methods of the ignition laser according to the invention provide that the integral connection of the insert to the combustion chamber window is effected by a soldering process.
  • a solder is provided, whose main components are silver and copper. The use of such a solder ensures that thermo-mechanical stresses between the joining partners in the solder can be taken plastic.
  • Main components were silver and copper and the titanium content of 2 wt .-% - 4 wt% had, also presented in long-term testing consistently very good results in terms of tightness and the thermo-mechanical load capacity of the joints.
  • solder material is punched out of a film by means of a punching device and inserted at the joint between the insert and the combustion chamber window. Subsequently, the soldering takes place under vacuum in a special centering device, which fixes the joining partners relative to each other.
  • the actual soldering is preferably carried out at a higher temperature than the baking and the sintering.
  • the soldering is carried out at a temperature which is above the hemisphere point of the material of the selected glass solder.
  • Alkaline earth borosilicate glass which has a proportion of Al 2 O 3 .
  • This glass solder is made by making glass powder into a paste with an organic binder system. Subsequently, this paste is applied by screen printing on the combustion chamber window 58. This is followed by heating of the organic constituents and sintering of the glass particles. The actual soldering takes place finally at a temperature which is above the hemisphere point of the glass solder.
