METHOD FOR INDUCTION HARDENING OF TILLAGE WORKING BODY Russian patent published in 2016 - IPC C21D10/00 C23C24/08 B23K13/01

Abstract RU 2582840 C1

FIELD: machine building.

SUBSTANCE: method for induction hardening of tillage working element is designed for use in agricultural, construction and other industries. Hard surface tillage working element part is applied charge containing, wt%: sormite grit 40-70, iron borides 30-60, with layer thickness from 0.5 to 5.0 mm. Thereafter, article is heated in inductor by HF currents at specific power of 0.8-5.0 kW per 1 cm² of surface with frequency equal to 1-80 kHz for 0.5-5 minutes before melting surface of charge. After heating of fusion bonded product is cooled in water.

EFFECT: higher wear resistance of tillage tool.
