FIELD: technological processes.
SUBSTANCE: invention relates to a method for thermal treatment of metals and can be used for production of wear-resistant structures when making working elements of tillage tools from high-strength cast iron HC 50. Tool surface is subjected to laser action with beam power P = 1.8 kW and with overlap coefficient of laser beam spot 0.3. Multichannel CO2-laser is used with continuous mode of operation. A laser beam spot of diameter d = 9 mm is formed. Beam travel speed makes υ=450 mm/s.
EFFECT: technical result consists in production of pure bleached layer of high hardness with depth of 0,1 mm.
