Preparation and characterisation of cattle bone based hydroxyapatite implant coatings using electrostatic spray deposition

The biocompatibility of orthopaedic or dental metallic implants can be significantly enhanced by the coatings of bioceramic materials. Currently, various deposition techniques such as plasma spraying, magnetron sputtering and pulsed laser deposition can be used for the metallic implant coating. Neve...
