Purpose: In this paper attention was paid to determine the corrosion resistance of Fe3Al intermetallic phase based alloy in corrosive medium of liquid hydrochloric acid with 0.2% concentration and sulphuric acid with 3% concentration. Research of material susceptibility to surface activation in the pipeline of corrosion processes are conducted. Work is continuation of earlier research of corrosion resistance evaluation tests for FeAl intermetallic phase based alloy in liquid HCl and H2SO4 corrosive medium. Design/methodology/approach: In the corrosion research electrolyser, potentiostat „Solartron 1285” and computer with „CorrWare 2” software were used. Results of the research were worked out with „CorrView” software. The potentials values were determined in relation to normal hydrogen electrode (NEW). The temperature of the solutions was kept on 21ºC level. The recording of potential/density of current - time curve was conducted for 300 s. Findings: The results of research conducted in 0.2% HCl solution, the best electrochemical corrosion resistance were showed by samples after annealing during 72 hours. It was confirmed by the lowest value of corrosion current density, low value of passive current density, pitting corrosion resistance much higher than in other samples. Practical implications: The last feature is the reason to conduct the research for this group of materials as corrosion resistance materials. Especially FeAl and Fe3Al intermetallic phase based alloys are objects of research in Poland and all world during last years. Originality/value: The goal of this work was to determine the influence of homogenizing treatment time on corrosion resistance of Fe28Al intermetallic phase based alloy in 0.2% HCl and 3% H2SO4 solutions. Homogenizing treatment was conducted in temperature of 1050ºC during: 24, 48, 72 and 96 h.
