Nitrogen ions (70 keV) were implanted on composite coatings containing polymer/Mg (magnesium)–Ag (silver) ions co-incorporated hydroxyapatite which was developed using microwave irradiation. Average crystallite size of modified coatings is reduced by 80% compared to the pristine. The variation of atomic bond strength of modified coatings is realized. The electrical resistance (77%), microhardness (4.3%), roughness (4.5 times) and pore size are enhanced on the nitrogen implanted coatings. Superhydrophilic surface is turned to hydrophobic on implantation. At higher fluence (1 × 1017 ions/cm2) depicted an enhanced corrosion potential compared to the other coatings. Thus, the new insight on modified coatings is elucidated by correlating phase-structure, surface and corrosion resistance.
