“…A similar improvement was observed in the nitrogen-implanted OT-4-0 alloy in 0.5 M NaCl and 1.5 M H 2 SO 4 media. Fukumoto et al [346] revealed that the lattice constant (a and c) of the titanium matrix calculated from the XRD peaks increased with higher nitrogen doses except for a at 1 Â 10 21 m À2 as shown in Fig. 53, indicating nitrogen dissolved in titanium matrix with increasing doses and TiN was subsequently precipitated.…”

“…Moreover, TiN is the material of choice as the hard coating on dental implants and dental surgical tools. The structure and properties of nitrogen ion implanted titanium and titanium alloys have been investigated by many researchers [344][345][346][347][348][349][350][351]. Krupa et al [344,345] implanted nitrogen into OT-4-0 (Ti-0.7Mn-0.7Al) titanium alloy using conventional ion implantation and investigated the changes of the surface structure and the advantageous effect of nitrogen ion implantation upon the corrosion resistance.…”

Titanium and titanium alloys are widely used in biomedical devices and components, especially as hard tissue replacements as well as in cardiac and cardiovascular applications, because of their desirable properties, such as relatively low modulus, good fatigue strength, formability, machinability, corrosion resistance, and biocompatibility. However, titanium and its alloys cannot meet all of the clinical requirements. Therefore, in order to improve the biological, chemical, and mechanical properties, surface modification is often performed. This article reviews the various surface modification technologies pertaining to titanium and titanium alloys including mechanical treatment, thermal spraying, sol-gel, chemical and electrochemical treatment, and ion implantation from the perspective of biomedical engineering. Recent work has shown that the wear resistance, corrosion resistance, and biological properties of titanium and titanium alloys can be improved selectively using the appropriate surface treatment techniques while the desirable bulk attributes of the materials are retained. The proper surface treatment expands the use of titanium and titanium alloys in the biomedical fields. Some of the recent applications are also discussed in this paper. #

“…Titanium (Ti) and its alloys have been widely exploited in medical device manufacturing [1][2][3][4][5][6][7][8][9], automotive production [10], aerospace frame construction [1] and armoured material fabrication [11,12]. The superior specific strength [1][2][3][4][5] and corrosion resistance [1,2,4,5,10,[13][14][15][16][17] of Ti-based alloys compared to many commonly available ferrous-and non-ferrous-based metals make them very attractive for such applications.…”

Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may have been made to this work since it was submitted for publication. A definitive version was subsequently published in Surface and Coatings Technology, In conclusion, a number of the surface modifications conducted have a beneficial affect on the wear resistance of Ti6Al4V. The process is also likely applicable to other metal/metal alloys such as CoCr, NiTi and stainless steels. Furthermore, the chemical-free nature and ambient temperature conditions concerned afford this process the potential to act as an attractive alternative to some of the more problematic high temperature approaches currently in use.

“…For conventional nitrogen ion energies ($100 keV), the thickness of the nitride layer is of the order of 100 nm. An important advantage of the nitride formation by the implantation is the good adhesion of the nitride layer to the substrate [8]. Another benefit of ion implantation for surgical materials is its ability to modify surface properties without almost no dimensional change compared with various coating methods such as PVD and ion beam assisted deposition [9].…”

a b s t r a c tNitrogen ion implantation can be used to improve surface mechanical properties (hardness, wear, friction) of stainless steels by modifying the near-surface layers of these materials. In this study, a medical grade FeCrNi alloy (316L stainless steel plate) was implanted with 85 keV nitrogen ions to a high fluence of 1 Â 10 18 N þ 2 =cm 2 at a substrate temperature <200°C in an industrial implantation facility. The N implanted layer microstructures, thicknesses and strengths were studied by a combination of X-ray diffraction (XRD), conversion electron Mössbauer spectroscopy (CEMS), atomic force microscopy (AFM) and nanohardness measurements. AFM was also used for the surface roughness analysis of the implanted as well as polished materials. The CEMS analysis indicate that the N implanted layer is $200 nm thick and is composed of e-(Fe,Cr,Ni) 2+x N-like nitride phase with mainly paramagnetic characteristics. The nanohardness measurements clearly indicate an enhanced hardness behaviour for the N implanted layer. It is found that the implanted layer hardness is increased by a factor of 1.5 in comparison to that of the substrate material. The increased hardness resulting from nitrogen implantation is attributed to the formation of e nitride phase.
