What is the advantage of the porous pure-titanium coating, applied under vacuum to the cementless components?
The three-dimensional porous structure of the titanium coating on the cementless components not only allows the bone to grow onto them but also to interlock. This ensures that the implant-bone interface withstands pressure forces and also shear and tensile forces. The vacuum process is used to prevent gas inclusions from forming at the boundary layer to the CoCrMo substrate, which would lower the bond strength of the coating.
