Abstract

Nitrogen ions (70 keV) were implanted on composite coatings containing polymer/Mg (magnesium)–Ag (silver) ions co-incorporated hydroxyapatite which is developed by microwave irradiation. Average crystallite size of modified coatings is reduced to 80% compared to pristine. The variation of 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 modified coatings. Superhydrophilic surface is tuned 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 of modified coatings is realized by correlating phase-structure, surface and anticorrosion.
