“…Generally, the TiO phase is observed after implantation with doses up to 1 Â 10 18 O + cm À2 between room temperature (RT) and 200 8C [331][332][333][334]. Hammerl et al [335] investigated the oxygen concentration distributions in titanium after implantation at temperature lower than À20 8C as a function of the implantation dose. Oxygen does not diffuse significantly at such low temperature and the local oxygen concentration can be as high as 70 at% as shown in Fig.…”

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. #

“…For the biomedically important class of Ti alloys, an outward diffusion of Ti is observed after both oxygen and nitrogen implantation, however with only moderate diffusion rates in the technologically important temperature range up to 500 °C [ 97 , 98 ]. At the same time, closed oxide and nitride layers are formed, respectively.…”

Ion implantation, a common technology in semiconductor processing, has been applied to biomaterials since the 1960s. Using energetic ion bombardment, a general term which includes conventional ion implantation plasma immersion ion implantation (PIII) and ion beam assisted thin film deposition, functionalization of surfaces is possible. By varying and adjusting the process parameters, several surface properties can be attuned simultaneously. Extensive research details improvements in the biocompatibility, mainly by reducing corrosion rates and increasing wear resistance after surface modification. Recently, enhanced bioactivity strongly correlated with the surface topography and less with the surface chemistry has been reported, with an increased roughness on the nanometer scale induced by self-organisation processes during ion bombardment leading to faster cellular adhesion processes.

ZrO 2 tends to be reduced to an oxygen-deficient zirconia (ZrO 2Àx ) in a reducing environment.…”

In this study, 3 mol% Y 2 O 3 -stabilized zirconia (3Y-ZrO 2 ) and commercially pure titanium (cp-Ti) joints were fabricated with an Ag 68.8 O layers were formed at the interlayer/ZrO 2 interface, while Cu 2 O was precipitated in the residual interlayer with 111 ½ Cu 2 O == 111 ½ Ag and 20 2 ð Þ Cu 2 O == 20 2 ð Þ Ag . After brazing at 900°C/6 h, a two-phase (a-Ti 1 Ti 2 Cu) region was observed on the Ti side with 2 1 10 ½ aÀTi == 100 ½ Ti 2 Cu and 0002 ð Þ aÀTi == 0 13 ð Þ Ti 2 Cu , while the TiCu layer grew at the expense of Ti 3 Cu 4 and TiCu 4 . The bonding mechanisms and diffusion paths were explored with the aid of Ag-Cu-Ti and Ti-Cu-O ternary phase diagrams.
