ABSTRACTAISI 316L stainless steel substrates were coated with hydroxyapatite [HAp, Ca10(PO4)6(OH)2]-seeded 58S bioglass, and then their in vitro bioactivity was evaluated by soaking in a simulated body fluid (SBF). The bioglass was prepared via the sol-gel technique and nanometric HAp single crystals were obtained by hydrothermal synthesis. The coatings had bioglass/HAp weight ratios of 100/0, 90/10 or 80/20. The in vitro bioactivity tests were carried out under static conditions at 37 °C and pH = 7.25, for time periods ranging from 1 to 21 days. The results showed that the HAp-seeding significantly accelerates the formation of a HAp layer at the bioglass-coated steel surface during the bioactivity tests.

Plasma Immersion Ion Implantation

Plasma immersion ion implantation (PIII) of nitrogen is low-temperature surface technology which enables the improvement of tribological properties without a deterioration of the corrosion behavior of austenitic stainless steels. In this paper the corrosion properties of PIII-treated AISI 316L stainless steel surfaces are evaluated by electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PP) and exposure immersion tests (all carried out in the 0.9 wt. % NaCl solution at 37 ± 0.5 °C) and compared with a non-treated surface. Results of the three performed independent corrosion tests consistently confirmed a significant increase in the corrosion resistance after two doses of PIII nitriding.

Aisi 316L Stainless Steel

This study investigates the in vitro corrosion and cytotoxicity response of AISI 316L stainless steel produced by powder injection molding (PIM) technology in a solution that simulates physiological fluids (MEM) by electrochemical techniques and neutral red uptake cytotoxicity assay. The results were compared with those of AISI 316L produced by conventional metallurgy. Both steels showed high corrosion resistance and no toxic effect in the cytotoxicity test. The corrosion products were analyzed by instrumental neutron activation analysis (INAA). The surfaces of the alloys were evaluated before and after corrosion test by scanning electron microscopy and a passive behaviour was indicated supporting the results from other techniques.
