Sol–gel and precursor-derived coatings with cover function on medical alloys†
Abstract
Various studies have reported detectable urine and serum levels of metal ions or their accumulation in organs or tissues of patients with metal implants. The concentrations of these ions are considerably higher in the tissue surrounding the implants. These ions may lead to systematic toxicity, carcinogenesis or allergic reactions, and influence the osseointegration and stability of the implants. Developments in the field of orthopaedic implants are in progress which involve covering the metal implants with a layer, which may limit the leakage of metal ions and reduce problems with loosening of the implants. In this study it is shown that sol–gel coatings (
