Fractal dimension used for evaluation of oxidation behaviour of Fe-Al-Cr-Zr-C alloys
Abstract
The article describes the possibility of using a methodology for the quantification of oxidised surfaces. The methodology is based on determining the parameters on a dividing line between alloy and air which has been generated from images of a cross-section sample. The parameters are obtained from the methodology using fractal geometry, surface roughness characterisation and statistic tools. The methodology is presented on oxidised iron aluminides (Fe-29.7Al-3.8Cr-0.3Zr-0.2C and Fe-26.4Al-2.8Cr-0.2Zr-0.6C) at high temperatures (900–1200 °C). The results show that methodology can be used for easy quantification of alloy oxidation attacks and for easy comparison of alloy oxidation resistance.
