Notes:
Apatite-mullite glass-ceramics have been developed as an alternative to hydroxyapatitefor use in vivo as a bioactive, osseoconductive biomedical alloy coating. In the cerammed state,they present a number of advantages including control over dissolution rates and mechanicalproperties by altering the composition of the parent glass or heat treatment regime. In the presentstudy, a simple sedimentation route was used to coat a biomedical titanium alloy, commonly usedfor orthopaedic applications. The material was deposited as a glass and cerammed in situ to create awell adheared coating that resisted delamination or cracking. To investigate the nature of thecoating-substrate reaction, a number of characterization techniques were used to examine thecrystallization behaviour of the glass, the glass-ceramic microstructure, and the interfacial reactionregion composition. The presence of products such as titanium silicides and unexpected pores areexplained by proposed reaction routes between the titanium and glass coating
