This work evaluates the effect of sodium meta-silicate pentahydrate (SMS) and potassium hydroxide concentrations on properties Al2O3-TiO2 coatings produced through plasma electrolytic oxidation in a solution containing 3 g L?1 titanyl oxalate, (PTO), using unipolar waveform with constant current density. The surface cross-section characteristics PEO including morphology, elemental distribution,...

In this research, the effect of PEO procedure time on the distinct properties of coatings such as morphology, chemical composition, roughness and corrosion has been studied. A scanning electron microscopy equipped with an energy dispersive spectroscopy was used to study the microstructure of the coatings. In addition, x-ray diffraction (XRD) and roughness meter were used to evaluate the chemica...

Titanium (Ti) is a material frequently used in orthopedic applications, due to its good mechanical properties and high corrosion resistance. However, formation of a non-adherent fibrous tissue between material and bone drastically could affect the osseointegration process and, therefore, the mechanical stability of the implant. Modifications of topography and configuration of the tissue/materia...

REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulations demand for an expedient discovery a Cr(VI)-free alternative corrosion protection light alloys even though the green alternatives might never be as cheap current harmful technologies. In present work, flash- plasma electrolytic oxidation coatings (FPEO) with process duration < 90 s are developed on AZ31B ...

This study was conducted to evaluate the bioactivity of manganese-incorporated TiO2 (Mn-TiO2) coating prepared on titanium (Ti) plate by plasma electrolytic oxidation (PEO) technique in Ca-, P- and Mn-containing electrolytes. The surface topography, phase and element compositions of the coatings were investigated using scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispe...

Recently, PEO process of tantalum has been developed as a method of producing corrosion-resistant, hard, wear-resistant, and biocompatible as well as having good adhesion coatings. In this review, we present the results of PEO process of tantalum in three main electrolytes. This review tries to measure the effect of electrolyte composition and voltage that were used within PEO procedure on the ...
