FIELD: technological processes.
SUBSTANCE: invention relates to tool industry, in particular to methods of processing a ductile tool from zirconium dioxide ceramics (zirconium dioxide-based ceramics ZrO2-Y2O3-ZrO). The method of laser processing of ductile tool from zirconium dioxide the tool surface is subjected to pulsed laser action, each pulse group of which forms a laser beam spot with a certain power of the beam on a sample, with the laser beam spot overlap ratio in the range from 0.1 to 0.9. The treatment is performed with the pulse repetition rate from 120 to 130 kHz, with the number of pulses in a group 95 and a power beam of the sample from 12 to 13 watts. Optimally, when the surface of the tool is subjected to pulsed laser irradiation from a laser beam spot overlap ratio in the range from 0.3 to 0.5.
EFFECT: increase of durability of ductile tools.
