ABSTRACT

Here, we shall discuss the basics and history of plasma spraying in general and microplasma spraying in particular. The method of hydroxyapatite (HAp) coating deposition by different techniques and the relative merits and demerits of those will be also described. The difference between conventional atmospheric high-power macroplasma and microplasma will be highlighted to demonstrate that such differences can and do indeed lead to significant changes in the correspondingly deposited HAp structures.
