Abstract

The influence of surface preparation of steel 41Cr4 on the structure and corrosion resistance of the zinc coating has been presented in the paper. The aim of the study was to determine the method of surface preparation fittings for overhead power lines made of steel 41Cr4 guaranteed to obtain zinc coating of a required thickness and high corrosion resistance. The prepared materials were subjected to an abrasive blasting - steel shot GL40 and chemical treatment - pickling (hydrochloric acid) and fluxing (TIBFLUX60). The hot - dip zinc galvanizing process was conducted in industrial conditions in 457 oC. The (Zn) - coating morphologies and sub-layer thicknesses were evaluated on the basis of metallographic analysis. The correlation between the results of corrosion test and coatings morphology was determined.

Keywords: Surface preparation, abrasive blasting, chemical treatment, hot-dip zinc galvanizing, corrosion resistance
