A review of hydroxyapatite-based coating techniques: Sol-gel and electrochemical depositions on biocompatible metals

New promising techniques for depositing biocompatible hydroxyapatite-based coatings on biocompatible metal substrates for biomedical applications have continuously been exploited for more than two decades. Currently, various experimental deposition processes have been employed. In this review, the t...
