Plasma Spraying of Hydroxyapatite
Hydroxyapatite, (HA), is a calcium phosphate bioceramic material which has an almost identical chemical composition to that of the mineral component of bone. The plasma spraying technique, a thermal spray process, is the most commonly used method for the production of HA coatings for orthopaedic applications. This process is a complicated one, affected by a large number of parameters. Due to this complexity, the process – property – structure relationship is poorly understood. This project aimed to clarify this relationship and use the knowledge gained to develop a novel bi-layer coating.
