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.

Research on the effect of ion implantation on the corrosion behaviour of metals has been carried out for years, but some difficulties arise in the comparison of the obtained results due to variations in experimental conditions (alloys, surface preparation, doses, experimental techniques...). This work tries to overcome those differences, presenting the effect of several elements (Ce+, N+, Cr+ and Cr+ N+) implanted in similar conditions on the pitting corrosion resistance of AISI 430 stainless steel. Potentiodynamic measurements in 1M NaCl demonstrate the beneficial effect of all the implanted elements, showing that Ce+ is the less efficient ion, while Cr+ N+ co-implantation gives the best results in terms of localized attack resistance. Pitting morphology is explained in terms of the XPS and GIXRD data that allow chemical and structural characterization of the implanted layer. Those results help to enlighten the protection mechanisms involved in the considered implantations.

Treatment Techniques

In spite of the success of surgical implants such as artificial hip joints, the materials used to make them are not always quite up to the job. Even stainless steel and titanium alloys can break under the enormous stress on load-bearing joints and corrode in the salty environment of the body. Deposits of inorganic salts can scratch weight-bearing surfaces, making artificial joints stiff and awkward. As a result, the lifetime of an implant is, at most, 10–15 years.Metallurgists and engineers often treat the surfaces of metal parts to improve their properties. The use of advanced surface-treatment techniques such as glow-discharge ion implantation, plasma deposition, and plasma coating can significantly improve the strength, hardness, and corrosion resistance of metal implants. At the same time, these methods should also improve the biocompati-bility of the implanted devices.Cobalt-based alloys are widely used for joint replacements. However, other compounds, such as titanium alloys, have excellent potential biocompatibility and interesting but imperfect mechanical properties. Stainless steel, namely 316L, has a good price-to-mechanical-properties ratio, but has the lowest corrosion resistance of the most commonly used metallic biomaterials.

AbstractThe manuscript focuses on the study of corrosion resistance in NaCl medium of a 304L type stainless steel after application of protective nickel-based and cobalt-based coatings produced by powder spraying under a continuous CO2 laser (10.6 µm wavelength) beam. Using polarization and electrochemical impedance spectroscopy methods, the results found confirm that metallic coatings produced under high energy beams offer excellent protection up to an efficiency of E = 98.12% in aggressive environments with salinity to 3%.
