METHOD OF WEAR RESISTANCE INCREASE OF PLOUGHSHARE Russian patent published in 2008 - IPC A01B15/04 B23K28/02 B23K9/04 B23P6/00 C21D9/50

Abstract RU 2334384 C1

FIELD: agriculture.

SUBSTANCE: electrode material is distributed over the most wearing part of the working surface by U-shape rollers or rollers having the shape of semiellipse. Beading is carried out continuously followed by fast cooling of the edge in water in order to form hardening structure.

EFFECT: increase of endurance ploughshare, decrease of friction coefficient and runout.
