Definitions

  • the invention relates to a method for producing metallic components by means of the sintering technique, in particular for producing components exposed to heat during use, such as covers for gas burners of domestic and commercial cookers or the like, and to a corresponding component.
  • the object of the invention is to provide a solution with which such components are easy to manufacture even with complex designs and offer an optical appearance which corresponds to today's requirements.
  • this object is achieved according to the invention in that a component produced by sintering is subsequently provided with an enamel layer at least in some areas.
  • a powder mixture with the base powder iron and alloy elements such as carbon, nickel, silicon oxide or silicates of the alkaline earth or alkali groups is recommended as the sintered material, the alloy additions expediently being below 5%.
  • the sintered components should have a weight of 5 to 8 g / cm3 and expediently have a residual porosity which is approximately 5 to 35% based on the theoretical density of iron.
  • the roughness of the surface structure before the application of the enamel layer can advantageously be 5 to 50 ⁇ .
  • the invention also provides components produced by the preceding method, these not being on the burner cap restrict, but here the invention is of particular value.
  • a burner generally designated 1 and partially sectioned in FIG. 1, has, in addition to the burner cover 2 in the foreground with an enamel coating 3, a burner stand 4 which passes through a gas trough designated 5, and further components.
  • the other components are, for example, a plug-in attachment 6, a burner ring 7 with the gas outlet channels 8 and, if appropriate, with additional gas outlet openings 9, but this is not important here.
  • the burner cover 2 can be designed to be very different, for example having a comparatively small inflow cone 10, as in the example in FIG. 1, a large inflow cone 10a in accordance with FIG. 2, or a smooth lower edge 10b, as in FIG. 3.
  • the lid 2c is equipped with an upwardly curved inner surface 10c.
