Examining the formation and properties of TiO2 oxide coatings with metals of iron triad

Application of oxide-metallic catalysts on valve metals for ecological catalysis

“…As was previously demonstrated [23], the introduction of cations of iron triad into the composition of electrolytes for PEO-treatment of titanium alloys makes it possible to obtain oxide systems with a different content of dopants in the surface layer. In this case, using the complex electrolytes particularly helps to improve the stability and operational lifecycle of working solutions [17,29], and contributes as well to a more uniform distribution of doping components on the surface of the treated material.…”

“…The study results helped to establish that the characteristics of stages of PEO-treatment of valve metals to form catalytically active layers depend on the nature of the treated material and the electrolyte composition [23,27].…”

“…3, a-c). The surface consists of spheroidal grains alternating with tubular microporous structure characteristic of TiO 2 [23].…”

“…Thus, in paper [23], authors studied the properties of mixed oxide-metallic coatings of titanium with the metals of iron triad (Fe, Co, Ni). It is shown that the introduction of dopants affected the structure and surface morphology of the synthesized oxide-metallic systems.…”

Study into formation of cobalt-containing peo-coatings on АК12М2МgN from a pyrophosphate electrolyte

“…Plasma-electrolytic treatment of aluminum in borate electrolytes allows obtaining oxide coatings with high micro-hardness [14]. The introduction of transition metals to the composition of surface oxide layers considerably improves catalytic properties of PEO-coatings in the reactions of decomposition of toxic components [15,16].…”
