Influence of a metal-oxide modifying mixture in ultrafine powder form on the physicochemical characteristics of IChKh28N2 cast iron

Abstract

Wear-resistant IChKh28N2 cast iron is investigated by X-ray spectral phase analysis and scanning electron microscopy, with and without the introduction of a modifying mixture (d-metal oxides in the form of ultrafine powder and nanopowder) and cryolite (Na₃AlF₆) reducing agent. The elementary and phase composition is determined; the microstructure of the metal matrix and eutectic is studied. The introduction of a modifying mixture and cryolite reducing agent changes the morphological structure, shifts the ratio of the basic phases, reduces the corrosion rate, and increases the corrosion resistance.
