Definitions

  • a device for accomplishing this method is also provided.
  • the present invention relates to a method and a device for local electric-spark layering of metals and alloys by means of a rotating electrode.
  • Some methods are known for electric-spark layering of metals and alloys upon contact and layering on other surfaces by means of a electrode vibrating perpendicularly to the surface and moving on it.
  • the coatings obtained according to the aforementioned methods lack uniform thickness, and suffer from the limitation of the layered area and a sufficient density.
  • the results obtained are not reproducible and depend to a great extent to'the skill of the operator. Accordingly, these methods are generally unsuited for uniform coatings on local areas which is necessary, for example, in the fields of electronics and radio engineering, which make use of relatively expensive manual devices.
  • the coating is layered by means of the butt of the layering electrode, which is rodshape and having a diameter of less than 2 mm. This is accomplished by rotating the butt around its axis, supported at an optimal distance from the layered portion in function of the disruptive voltage and the current.
  • the electrical impulses are of about 15 to about 600 volts (idle running) with a duration of l to microseconds.
  • the motion of the electrode must be planetary of controllable speed and radius. In this case, it may be necessary that the layered portion must be moved planary.

  • the layering electrode is rodshaped and under 2 mm of diameter, and is fastened to the layering head and rotated around its axis by an incorporated electromotor in the said head, which is moved with the head axially by means of a following up system. This assures an optimal distance between the butt (contact point) of the layering electrode and the fastened on the table layered portion. Both are supplied by the electrical impulses generator.
  • the generator of the electrical impulses should be connected with the layering electrode by means of a mercury current supplying device and the electrical impulses should be of controllable paramaters: idle running voltage from 15 to 600 Volts and the duration of the impulses from I to 10 microsec.
  • the device should posses a mechanism ensuring a planetary motion of the rotating and layering electrode with controllable speed and radius to obtain coatings with a width larger than the diameter of the layering electrode or for obtaining ringshaped and other coatings.
  • the layering device must be equipped with a mechanism for planar moving of the table and the layered detail fastened on it by a programming facility.
  • the method and the device of the invention for electric-spark layering of metals and alloys ensures the obtaining of local high quality dense coatings in a programming cycle and automatic maintenance of the optimal technological parameters of the regime and high productivity.

  • the platform shaped coating 3 is fo a diameter equal twice the diameter of the layering electrode 1.
  • FIG. 3 shows the principle of the local electric-spark layering of coatings by means of a rotating around its axis and planetary moving layering electrode 1, with a radius of the planetary motion larger than the radius of the layering electrode, at which conditions the coating 3 has a form of ringshaped band.
