Effect of Chromium on the Surface Tension of Fe-C-Cr Model Alloys

Original language description

The presented paper is focused on the experimental study of the surface tension of selected Fe-C-Cr model alloys. The surface tension was measured by the sessile drop method in the temperature interval from the melting point of the given model alloys to the temperature of 1,600oC. The effect of the temperature and the chemical composition on the surface tension of the model alloys was studied. Therefore, the model alloys with different chromium content (0.92 - 4.76 wt. %) were chosen for an examination of this influence. Experimental surface tension measurements were repeated for each sample and then statistically evaluated by statistical computing environment R (R Core Team (2018). R: A language and environment for statistical computing. R Foundation for Statistical Computing, Vienna, Austria. URL https://www.R-project.org) to assess the reproducibility of the measured data. During evaluation of the surface tension dependence on temperature, it has been shown that the surface tension of the alloys increased slightly with the increasing temperature, i.e. that the temperature coefficient of the surface tension dσ/dT was positive. The positive character of the temperature coefficient can be attributed to the presence of the surface-active elements, especially the sulphur, in the selected samples. It was found that the surface tension of the alloy samples also raised with the increasing chromium content.
