“…With regard to orthopedic implants also, different surface modification methods have been adopted to improve their corrosion resistance [109,110,[111][112][113][114][115]. Thair et al studied the corrosion behavior of nitrogen ion implanted Ti-6Al-7Nb alloy by varying the dose of the nitrogen ions using an accelerator [116].…”

In the area of materials science, corrosion of biomaterials is of paramount importance as biomaterials are required for the survival of the human beings suffering from acute heart diseases, arthritis, osteoporosis and other joint complications. The present article discusses various issues associated with biological corrosion of different kinds of implants used as cardio stents, orthopedic and dental implants. As the materials used for these implants are manifold starting from metallic materials such as stainless steel (SS), cobalt chromium, titanium and its alloys, bioceramics, composites and polymers are in constant contact with the aggressive body fluid, they often fail and finally fracture due to corrosion. The corrosion behavior of various implants and the role of the surface oxide film and the corrosion products on the failure of implants are discussed. Surface modification of implants, which is considered to be the best solution to combat corrosion and to enhance the life span of the implants and longevity of the human beings is dealt in detail and the recent advances in the coating techniques which make use of the superior properties of nanomaterials that lead to better mechanical properties and improved biocompatibility are also presented.

“…Such biomaterials often cause allergic reactions by releasing toxic ions and particles (Ni + , Cr 3+ , and Co 2+ ), which causes inflammation and promotes corrosion within the host tissues. The chances of corrosion increase as these implanted materials are always in direct contact with the bloodstream and aggressive body fluids [5][6][7][8].…”

The article focuses on the corrosion behavior of medical grade 316L stainless steel used in cardiac stents, orthopaedic, and dental implants. In this research work, electro-discharge treatment (EDT) was used for the deposition of titanium dioxide (TiO2) particles on 316L stainless steel to improve its corrosion-resistant property. The samples were characterized using scanning electron microscopy and x-ray diffraction techniques to correlate the modified surface with the EDT process parameters. The electrochemical corrosion analysis shows a lower corrosion rate for the TiO2 coated specimen (1.883 mpy) compared to the untreated surface (13.729 mpy). This improved corrosion resistance of TiO2 coated substrate was attributed to the formation of various silicides, carbides, and bioactive compounds.
