Novel interlocked bioactive coating on metallic substrates for orthopaedic applications

对于在金属基底上制备用于骨科应用的高完整性生物活性涂层存在显著需求。当前技术产生的伪影在植入和随后的性能期间易于因剪切而失效。这对NHS来说是非常昂贵的，对必须接受翻修手术的患者来说也是非常痛苦的。在这个项目中，我们正在测试一个新的程序，这将产生一个互锁的涂层基板地形。这种新的涂层程序将被优化，并在涂层-基材界面处的剪切强度将被测量，并与当前技术生产的试样进行比较。目的是将新技术商业化。

There is significant demand for preparing high integrity bioactive coatings on metallic substrates for orthopaedic applications. Current technology produces artefacts which are prone to failure by shear during implantation and subsequent performance. This is very costly to the NHS and very distressing to patients who have to undergo revision surgery. In this project we are testing a new procedure which will generate an interlocked coating-substrate topography. This novel coating procedure will be optimised and the shear strength at the coating-substrate interface will be measured and compared with that of specimens produced by current technology. The aim is to commercialise the new technology.
