A method of producing layered, adhesively bonded hydroxyapatite coatings is described. The coatings have a flexible polymeric interlayer which can improve load transfer from the implant to the bone, and a hydroxyapatite-rich surface which can provide mechanical interlocking with the bone. The coatings have been characterized using a number of methods including optical and electron microscopy, mechanical testing and finite element analysis. Some ways in which the coatings could be used to produce orthopaedic implants with improved mechanical and biological compatibility are discussed.
