Pitting areas percentage (% Area) on alloys’ surfaces tested in static and dynamic conditions.

The pittings were observed by SEM on surfaces of Non-coated, PCUU, PLGA coated alloys after removing attached endothelial cells, left coating and corrosion products. The pitting areas and percentage on alloys surfaces and under coatings were calculated with ImageJ software. * represents the significant difference of between pitting area percentages of Non-coated, PCUU and PLGA coated alloys on same alloy’s surface (P<0.05).
