METHOD OF RESTORATION OF CULTIVATOR BLADE WITH SIMULTANEOUS STRENGTHENING ITS WORKING SURFACE

摘要

FIELD: agriculture.SUBSTANCE: worn working part of the restored blade is removed. A new corner plate is made of spring steel, its sharpening is carried out to form a blade and it is welded to the restored cultivator blade. Electric vibrating arc strengthening of the corner plate is carried out using a paste containing powder of type PG-10N-01, tungsten carbide and cryolite. The paste is applied to the surface of the corner plate opposing relative to the blade and after solidification is melted using an electric arc with use of a graphite electrode, and the current is 90-95 A, the voltage is 55-60 V.EFFECT: increase in impact strength and durability of restored and strengthened parts of tillers.1 tbl
