Abstract

The structure and phase composition of geomodifiers coating obtained on the surface of steel balls are examined using optical metallography, SEM and XRD. Coating has been formed for 672 hours by mixing of serpentine powder with steel balls in a ball mill. The coating has an adhesive bond to the substrate. The phase composition of the coating is different from the phase composition of the initial powder. The formation of the magnesium silicate is caused by the process of dehydration. Dehydration occurs due to local temperature fluctuations in the contact areas of the steel framework and serpentine in their interaction. It was determined that for formation of the coating of certain phase composition cumulative release of heat must meet the heating temperature higher than 550°C.
