METHOD OF PRODUCING STEEL NANOSTRUCTURED SURFACE BY LASER-INDUCED PLASMA PROCESSING Russian patent published in 2012 - IPC B82B3/00 C23C4/12 B23K26/34 C21D1/09

Abstract RU 2447012 C1

FIELD: process engineering.

SUBSTANCE: invention relates to metal processing by laser and may be used in machine building. Part to be processed is placed in sealed chamber filled with inert gas and modifying gas. Laser beam with spot power density on part surface making (10⁶-10⁷) W/cm² is used to affect steel part surface to produce optical discharge surface plasma in fused metal vapors. Laser beam is displaced at the speed of 0.1-2 m/s at gas pressure in the chamber equal to 1.5-2 atm.

EFFECT: improved mechanical properties, higher wear and heat resistance.
