The mechanical life of implements operating in corrosive service

Abstract

In severe operating conditions, there are machines for the preparation and introduction of mineral and organic fertilizers, herbicides, pesticides. They fail in order after two or three years due to corrosion and corrosion-mechanical wear. Under these conditions, the main thing is not to protect individual details, but the protection of the machine as a whole. Disclosure of the mechanism and patterns of corrosion-mechanical wear and corrosion of structural materials in aggressive environments made it possible to scientifically substantiate the most effective ways to increase the service life of machines at the stages of design, manufacturing and operation. Passive working bodies (frame, body, tank) polymer and gummed coatings are reliably protected from corrosion. Corrosion damage to the details of agricultural machines during storage. The illustrated surfaces of the working bodies of plows, seeders, cultivators, disk harrows and other agricultural machines in the storage period are oxidized and coated with rust. In some cases, it appears due to the destruction of the protective film of paint in others - due to violation of the storage rules. The lower parts of agricultural machines made of simple carbonistic structural and unfounded steels, in contrast to parts remote from the soil and no contact with it, corroded intensively.
