PLOUGHSHARE STRENGTHENING METHOD Russian patent published in 2012 - IPC C21D9/18 C21D1/06 C21D1/40

Abstract RU 2460810 C1

FIELD: metallurgy.

SUBSTANCE: during electromechanical processing on ploughshare surface there formed are parallel strengthening zones with hardening structures of high hardness level. Strengthening zones with depth of up to 3 mm and width of 3.5÷7 mm are located at an angle of 40÷55° to ploughshare blade at the distance between them of 10÷30 mm. As a result of the above method the additional materials are not consumed and further mechanical processing is not required.

EFFECT: increasing lifetime of ploughshares due to improving their strength characteristics and wear resistance to abrasive wear.
