Abstract: (289 Views)
The study employed sequential DC plasma electrolytic oxidation on morphology and behavior of coatings on CP titanium. The coatings formed in two steps first in silicate, next in calcium phosphate. The influence of second step coating in silicate and calcium phosphate electrolytes on morphology, phase structure and corrosion behavior were studied using SEM followed by EDS, XRD and polarization. Due to low thickness coating in silicate electrolyte and increasing applied Voltage, coatings formed in calcium phosphate have a low size porosity compare to coating formed in silicate electrolyte and in turn revealing an improvement in corrosion resistance. Unlike coatings formed first in calcium phosphate then in silicate electrolyte, the size of porosity increased and corrosion resistance has been decreased.
