METHOD OF ANTICORROSION TREATMENT OF FERROUS METAL SURFACE

摘要

FIELD: machine building.SUBSTANCE: primer-corrosion converter of ferrous metals comprising orthophosphoric acid and zinc oxide is mixed with basic gallate of bismuth upon presence of ecologically safe complex based on ethylenediamine disuccinic acid.EFFECT: use of suggested composition of the converter the anticorrosion resistance of the ferrous metals is significantly increased, also production effectiveness and corrosion protection of the ferrous metal products are improved.2 tbl
