A self-optimizing electrodeposition process for fabrication of calcium phosphate coatings

A self-optimizing electrochemical deposition method, named cathode rotation electrodeposition process, is put forward in this work for the fabrication of calcium phosphate coatings. Because the metallic substrate rotates with high speed, the centrifugal and friction forces could clear away hydrogen bubbles and poor-adhesion deposition particles produced on the substrate in due course. The process possesses a self-optimizing character, and only deposition particles with enough bonding strength can be selected as coating units. Compared with conventional electrodeposition process, this novel process could provide us with more compact and homogeneous calcium phosphate coatings on the substrate. (C) 2001 Elsevier Science B.V.
