Development of strontium and magnesium substituted porous hydroxyapatite/poly(3,4-ethylenedioxythiophene) coating on surgical grade stainless steel and its bioactivity on osteoblast cells

- The bilayers of PEDOT/Sr, Mg-HA were achieved by electrodeposition on 316L SS.
- These coatings were characterised by cyclic volatmmetry, FT-IR and HRSEM.
- SEM morphology reveals porous Sr, Mg-HA layer on PEDOT coated 316L SS.
- As-formed bilayer demonstrates enhanced corrosion protection in Ringer's solution.
- PEDOT/Sr, Mg-HA bilayer coating exhibited better cell adhesion.
