Metalline compounds as excess phases, corrosion-resistant materials, and protective coatings

Abstract

in Fig. 3 reflects the relationship of the total solution rate iaE of Fe-Cr alloys (with a constant potential) to their composition with pH = 0. It may be seen that under these conditions with an increase in chromium content in the alloy iaE first increases and then reaches a limit~

Improvement of physical and chemical properties of steel implanted with Cr+, Ti+, Si+ ions

“…It is still an open question under which implantation condi tions the most advantageous changes of the corrosion characteristics may be obtained. However, the forma tion of chemically modified surface and subsurface layers with high strength Me-С and Me-Si (Me = Fe, Ti, Cr) covalent bonds seems to play an important role in this context [10]. The surface modification with corrosion resistant components (Cr+, Ti+, Si+) on the one hand decreases the anodic reaction rate on the implanted steels, and on the other hand the passivation ability of implanted steels is increased as a result of formation of transition metal carbide and silicide pre cipitates which change the reaction kinetics.…”
