Pulsed electrochemical deposition of calcium phosphate coatings for biomedical applications

Calcium phosphate coatings have been widely used in orthopaedic and dental implants due to their excellent bioactivity and ability to promote formation of new bone tissue. Among the techniques used to manufacture these materials, electrochemical deposition has emerged as a promising method due to several benefits, such as improved compositional control, coating uniformity, versatility, and low cost. Moreover, the use of a pulsed current has proved to be an effective strategy to overcome electrochemical deposition's major shortcomings. Herein, we provide an overview of the electrochemical deposition method, highlighting the benefits of the use of a pulsed current, as well as discussing the recent advances in the field. Overall, pulsed electrochemical deposition represents a promising approach for the production of high quality calcium phosphate coatings tailored for orthopaedic and dental implants.
