Purpose:Purpose alloys on intermetallic phase matrix of iron and aluminium are considered the future materials for high-temperature applications as they are highly resistant to oxidation. Oxidized intermetallic alloy FeAl forms a protective alumina layer. The paper presents results of tests concerning kinetics of corrosion processes of alloy on intermetallic phase matrix FeAl of the composition Fe40Al5CrTiB after casting and plastic treatment with the use of co-extrusion method. The aim of this paper was to determine the resistance to high-temperature corrosion in atmosphere of air for alloy Fe40Al5Cr0.2TiB. Design/methodology/approach: Corrosion tests were conducted in temperatures 900, 950 and 1000°C in time 8 hours, kinetics of corrosion appointed on the thermogravimetry method. The condition of the surface of samples after tests was characterized with the use of electron scanning microscope and also the chemical composition of corrosion products was determined. Findings: Conducted tests have shown a high corrosion resistant alloy Fe40Al5CrTiB in comparison. The resulting graphs show the kinetics of corrosion processes on the parabolic character of the process of creating high-temperature corrosion products. Practical implications: The Al alloy have a high corrosion resistant with resistant conventional materials predestined to do work in high temperature in corrosion environment. Originality/value: The aim of this paper was to determine the resistance to high-temperature corrosion in atmosphere of air for alloy Fe40Al5Cr0.2TiB.
