Now very actual task is identification of material resources. The sputter-ion method of drawing identification tags can be used for protection against a counterfeit of electroconductive parts, for example, of products of rolling, parts of vehicles, products of mechanical engineering, aircraft industry, products of the defense industry, etc. Many methods of drawing tags are difficult and energy-intensive. The created tag can easily be erased and the new ways of processing ensuring safety of the placed information on a part surface are necessary. The identification tag on metal is created by implementation of electric discharge between a high-voltage electrode and the carrier, and the electrode is moved up and down information grid under the law of random numbers, with the subsequent drawing a digital code and information grid. As information grid use the metal filter, and choose discharge energy from a condition of evaporation of sites of this filter under the influence of a spark discharge. Discharge energy is chosen in the range from 0,5 to 12 J at pulse width from 10- 4 to 10- 3 sec. Any other physical information grid executed, for example, on continuous metal will demand in the mechanical or electroerosive way much more energy on forming of completely evaporated sites. At introduction of energy on a grid a spark discharge, currents on elements of a grid are distributed depending on the contact resistance which has stochastic character, as cause‘s accidental sites of evaporation. During the researches it was found out that when processing the filter discharge energy less than 0,5 J the evaporated sites are not registered, instead of them there are dark sites of the melted-off zones which can also be used as identification signs. However reliability of scanning of such sites is slightly lower, than scanning of the sites which are carried out "on a gleam". Further increase in discharge energy over 12 J is inexpedient. Further an object with a tag is photographed (scan), bring the received image in the computer and assign it the identification number. Technical result of application of this way is increase in reliability of storing of information because as information grid use the metal filter, and discharge energy is chosen from a condition of evaporation of sites of this filter. New way of creation of an identification tag on metal more highly productive, also allows creating by means of surface electric discharge is information the saturated branchy drawing of not repeated matrix. |
