Influence of Carbon and Nickel on Surface Properties of Fe-C-O-X (X=Cr, Ni) Alloys
Original language description
This paper deals with an experimental determination of surface tension, densities and wetting angles, which were considered for spreading on an alumina substrate, of selected Fe-C-O-X (X = Cr, Ni) alloys. The concerned physico-chemical quantities were determined by a sessile drop method in the temperature interval between liquidus temperature of the given alloy and temperature of 1,600 oC during heating with a rate of 5 oC.min-1. Several Fe-C-O-Cr and Fe-C-O-Ni model alloys differed in carbon (0.043 - 1.378 wt.%) and nickel (1.084 - 4.478 wt.%) content in order to assess the effect of these elements. From the dependence of surface tension on temperature, it was found that the surface tension of given alloys increases slightly with increasing temperature, i.e. that the temperature coefficient of surface tension dσ/dT was positive. Similar course was ascribed regarding wetting angles dependence on temperature. Further, the influence of carbon and nickel on surface properties was proved by statistical analysis carried out in the R environment for statistical computing and visualization.
