Book excerpt: Hydroxyapatite, (HAP), a calcium phosphate bioceramic material, has been widely used in both dentistry and orthopedics due to its biocompatibility and osteoconductivity. However, its poor bulk mechanical properties have limited its use as load bearing material. An effective approach to solve this problem is to form a composite coating of HAP and titanium, in which titanium will be the matrix and HAP will act as reinforcement. In this research, two novel approaches, namely cold gas dynamic spraying (CGDS) and argon atmosphere plasma spraying (AAPS), were applied to manufacture HAP/Ti composite coatings. The aim was to produce thick and dense deposits and investigate the mechanical, electrochemical and incubation behavior of such biocomposites as potential load bearing materials for biomedical applications.
