Surface Tension and Wettability of selected Steels with Alumina Substrate

Popis výsledku v původním jazyce

The presented paper is focused on the experimental study of the surface properties of selected real steel grades. The surface tension of given steels and their wetting with alumina substrate in the temperature interval from the melting point to the temperature of 1600 °C were determined using the sessile drop technique. The effect of the temperature and the chemical composition on the surface properties of the steels was studied. For an assessment of the influence of the major elements (carbon and chromium) the steels with different carbon and chromium contents, which varied in the range of 0.077 - 0.411 wt. % and 0.049 - 12.392 wt. %, respectively, were selected. It was shown that with an increasing content of both aforementioned components increased the surface tension of the investigated steels and the contact angle with alumina substrate. The temperature dependencies of surface tension exhibit a steeper decrease at higher chromium contents.
