Thickness of APS (atmospheric plasma spraying) coating can be selected between 50 and 250 pm, depending on application however, novel deposition techniques such as suspension or solution plasma-spraying allow coatings with thickness <10 pm.

Microstructural analysis of suspension plasma sprayed Ti02 coatings by Raman spectroscopy and transmission electron microscopy correlated well with results obtained by XRD. The anatase content in the coatings varied between 10 and 22 mass%, dependent on spraying parameters. Raman spectroscopy enabled the imaging of the spatial 2D-distribution of the rutile and anatase (Podlesak et al., 2008). Transmission electron microscope enabled to visualise the contact areas between the lamellae inside sprayed coatings as well as the columnar growth of crystal inside the lamellae.

In the past few decades, plasma spray-coating techniques have been developed to cover orthopedic implants with protective and/or bioactive coatings. As introduced in Chapter 1, the plasma spray-coating method employs high temperature plasma jet to melt and spray a feedstock material onto a substrate to form a coating. The feedstock materials for plasma spray can be in the forms of solid, liquid or suspension [29,30]. For the fabrication of nanocoating on orthopedic implants, the commonly used solid...
