Methods of scanning electron microscopy with an X ray probe, Raman spectroscopy, and ther mogravimetry are used to study the morphology and composition of metal oxide nanocomposites obtained by intense plastic deformation of iron powder and the further annealing in the TGA mode. It is shown that high temperature annealing of activated powder deformation results in the formation of "hematite wood"a layer of "nanoflakes" and "nanoleaves" growing vertically on the composite surface. In addition to its intrinsic functional (sensor, catalytic, semiconductor, adsorption) properties, this structure possesses pro nounced primer properties for further formation of protective surface layers.

“…In this prior work, ferrous ions (Fe 2+ ) rather than ferric ions (Fe 3+ ) were used as the primary iron source in the electrodeposition baths. Electrodeposited Fe-Ni alloys other than Invar alloys, [23][24][25][26][27][28][29][30][31][32][33] and Fe-Ni system ternary alloys [34][35][36] other than Super Invar alloys, have also been widely researched, again mainly using Fe 2+ ions as the iron source. This procedure has become the standard because Fe 3+ ions readily form a minimally soluble hydroxide (Fe(OH) 3 , having a solubility product K sp of 4 × 10 −38 ) in aqueous solutions.…”

Fe-Ni alloy films with invar alloy compositions were electrodeposited from a stable citrate bath containing trivalent iron ions (Fe3+) as the sole iron source. This bath was prepared based on determining the equilibrium constants for acid dissociation, complex formation and precipitation reactions. The electrodeposition was conducted under galvanostatic conditions at 25°C without agitation and the effects of pH and current density on the composition and microstructure of the films were investigated. Ferric hydroxide (Fe(OH)3), which is normally poorly soluble, was found not to precipitate even after the electrodeposition. In addition, Fe-Ni alloy films containing 31‒42 mass% Ni (including Fe-36 mass% Ni) were formed with a current efficiency of approximately 70%. Although the films were smooth and comprised grains having sub-micron sizes, some cracks were observed in these specimens. Fe and Ni were distributed homogeneously throughout the films and the Fe-Ni solid solutions exhibited both face-centered cubic and body-centered cubic structures.
