A 70-year-old man with an uncemented metal-on-polyethylene total hip prosthesis underwent revision arthroplasty 33 months later because of pain, swelling and recurrent dislocation. There appeared to be corrosion and metal release from the prosthetic head, resulting in pseudotumour formation and severe local soft-tissue destruction. The corrosion occurred at the junction between the titanium-mol...

Various electrochemical approaches, including potentiodynamic polarization, open circuit potential evolution and electrochemical impedance spectroscopy (EIS), are employed to investigate the degradation behavior of biomedical magnesium alloy under the influence of aggressive ions, such as chloride, phosphate, carbonate and sulfate, in a physiological environment. The synergetic effects and mutu...

Microbially induced corrosion (MIC) is a complex problem that affects various industries. Several techniques have been developed to monitor corrosion and elucidate corrosion mechanisms, including microbiological processes that induce metal deterioration. We used zero resistance ammetry (ZRA) in a split chamber configuration to evaluate the effects of the facultatively anaerobic Fe(III) reducing...

A corrosion inhibitor suitable for industrial production and field application was rapidly synthesized from benzene-1,2-diamine, benzaldehyde, methanol, hydrochloric acid, and FeCl3. The mechanism of corrosion and its inhibition was proposed. We investigated the effect of the main reactants on corrosion rate, and optimal synthetic composition (benzene-1,2-diamine 10 g, b...

An experimental program was conducted to determine the mechanisms by which phosphorus affects the corrosion and passi~ation behavior of F e Cr P alloys, "lb idcnti~ separately the ell~cts of structure and chemistry on the corrosion behavior, thin tilms of Fe--ItK'r-xP 10 < x < 35 at.%) were I~-epared by ion beam mixing. Films with a phosphorus content greater than approximately 20 at.% were fou...
