“…15,16 Moreover, titanium nitrides coated by reactive plasma spraying exhibit high resistance to wear. 17,18 This suggests that the partial nitriding of the Ti splats in HA/Ti composite coatings improves the mechanical properties of the Ti networks in the HA/Ti composite and increases the bond strength of such coatings.…”

“…Our results clearly demonstrate that the composition of the plasma gas during rf-RPS played a crucial role in providing bioactivity to the Ti coatings we obtained. 7,8,27,28 Therefore, RPS-Ti coatings prepared with Ar-N 2 -O 2 plasma, which thus contain titanium nitride phases, may provide both high corrosion resistance and biocompatibility on titanium or titanium alloys used for artificial joint replacement prostheses or other medical applications. As confirmed by XRD analyses, both anatase and rutile phases formed on RPS-Ti coatings sprayed with plasma containing oxygen.…”

The in situ surface modification of Ti particles was conducted by making use of plasma-enhanced reactions between the Ti particles and the reactive gaseous species in the plasma flame during RPS. Surface-modified Ti coatings were deposited on Ti substrates by rf-RPS using a thermal plasma of Ar gas containing 1%-6% N 2 and/or 1%-6% O 2 . As a means of surface modification, Ti powders impregnated with 0.05-0.2 mol % Ca were also sprayed. Compositional changes in the coatings' surface after soaking in simulated body fluid ͑SBF͒ were evaluated by Fourier transform infrared spectroscopy and thin-film x-ray diffraction analyses ͑TF-XRD͒. The Ti coatings prepared with Ar-O 2 and Ar-N 2 -O 2 plasma formed bone-like apatite after three days of soaking in SBF. On the other hand, no compositional change was observed in the surface of the Ti coatings sprayed with Ar-N 2 plasma, even after seven days of soaking in SBF. In the TF-XRD patterns for the Ti coatings sprayed with oxygen-containing plasma, TiO 2 ͑anatase and rutile phase͒ were commonly observed. In SBF tests, we observed a retardation of apatite deposition for the Ca-added Ti coatings prepared with Ar-O 2 and Ar-N 2 -O 2 plasmas. Analyses by x-ray photoelectron spectroscopy indicated that the Ca impregnated in the RPS-Ti coatings formed a Ca-O compound.

“…Depending on the working atmosphere, the resulting species may be of oxide, nitride or carbide. Examples of this kind of coatings are those obtained from spraying of materials such as FeTiO 3 , whose resulting deposits are www.intechopen.com composed of Fe/TiC-Ti 3 O 5 ; and titanium Ti to obtain the deposition TiN, Ti 2 N, TiN 1-x , TiC or TiC 1-x (Ananthapadmanabhan & Taylor, 1999;Valente & Galliano, 2000;Lugscheider et al, 1997).…”
