Purpose: The purpose of the paper is to present corrosion resistance of composite materials Fe73.5Cu1Nb3Si13.5B9每 PEHD type in acid environment.Design/methodology/approach: Composite materials Fe73.5Cu1Nb3Si13.5B9 每 PEHD type were manufacturedby one-sided uniaxal pressing. Composite materials were placed in a corrosive environment and two tests werecarried out as specified below: test at the temperature of 25oC, solution of 0.1 M chloride acid HCl, time of 348h,test at the temperature of 25oC, solution of 0.1 M sulfuric (VI) acid H2SO4, time of 348h.Findings: The main purpose of obtaining this kind of composite materials is broadening possibilities ofnanocrystalline magnetic materials application that influence on the miniaturization, simplification and loweringthe costs of devices.Practical implications: The manufacturing of composite materials Fe73.5Cu1Nb3Si13.5B9 每 PEHD type greatlyexpand the applicable possibilities of nanocrystalline powders of magnetically soft materials however furtherexamination to obtain improved properties of magnetic composite materials and investigations of constructions ofnew machines and devices with these materials elements are still needed.Originality/value: Results allow to complete data concerning composite materials nanocrystalline powder每 polymer type which are an attractive alternative for traditional materials with specific magnetic properties.
