An ultrasonic technique has been developed for measuring the elastic moduli of bioceramic coatings applied to titanium orthopaedic implants. The bioceramic material (hydroxyapatite) is plasma-sprayed onto titanium femoral implants. The thin layer of this material facilitates bone bonding to the implant. The objectives of the present study were to develop a nondestructive method to observe changes in the mechanical properties of the coatings in a physiologically simulated environment.
