“…Therefore, the apatite-forming ability of Ti 40 Zr 10 Cu 36 Pd 14 BMG is rather low, even after pretreatment with alkali solution and a subsequence 15-day immersion in SBF. On the other hand, a porous sodium titanate reduced by the reactions between the Ti-coating and OH À ions 8) is found by SEM (Fig. 5) after alkali treatment.…”

In this research, Ti coating was conducted on Ti 40 Zr 10 Cu 36 Pd 14 bulk metallic glass (BMG) in order to increase the formation rate of hydroxyapatite layer. The formation behavior of bone-like hydroxyapatite on Ti-coated and uncoated Ti 40 Zr 10 Cu 36 Pd 14 bulk metallic glasses (BMGs) was studied. The surface morphology of Ti-coated and uncoated Ti 40 Zr 10 Cu 36 Pd 14 BMG was investigated by scanning electron microscopy and energy dispersive X-ray spectroscopy. The results revealed that the alkali pretreatment in 5 M NaOH solution at 60 C for 24 h had a beneficial effect on the formation of porous sodium titanate on Ti-coated Ti 40 Zr 10 Cu 36 Pd 14 BMG. A bone-like hydroxyapatite layer was able to form on the alkali-treated Ti-coated Ti 40 Zr 10 Cu 36 Pd 14 BMG after a short-time immersion in simulated body fluid (SBF). On the contrary, hydroxyapatite formation was not observed on the uncoated Ti 40 Zr 10 Cu 36 Pd 14 BMG after the same chemical treatments.

“…It has been reported that a TiN sputter-coating on Ti-6Al-4V alloy enhances wear resistance and corrosion performance in artificial hip joints. 8) Magnetron sputtering coating is not yet applied on BMGs. Therefore, the application of magnetron sputtercoating to BMGs materials is a totally new topic facing for all materials researchers.…”

“…Numerical techniques, such as the finite element method (FEM) and boundary element method (BEM), are also widely used in the analysis of contact mechanic problems with thin coating (Komvopoulos, 1988;Hong and Saka, 1991;Djabella and Arnell, 1993;Sun et al, 1995;Njiwa et al, 1998;Diao and Kandori, 2006). The thin-coating technique is generally used in structural components such as gears, bearings, machine tools, and artificial hip joints to improve their surface mechanical properties (Sen et al, 1989;Liu et al, 2003;Yonekura et al, 2005;Bruno et al, 2006;Martins et al, 2006). Therefore, in this paper, thin-coated joints such as ball and socket, ball on a flat plate, roller on a guide, and spur gear are analysed by FEM.…”

Abstract:The frictional contact of elastic solids with thin and moderately thick coatings is analysed by using the finite element method. It is assumed that 2 elastic, homogeneous substrates with elastic coatings are perfectly bonded and contact with each other under normal and horizontal forces. The coating and elastic substrate are modelled with 2D and 3D finite elements. After verifying the finite element solutions by analytical solutions, various geometric configurations are analysed such as ball and socket joint, ball on a flat plate, a roller on a guide, and spur gear. Different material combinations and coating thicknesses are considered in the coating-substrate system. Their effects on the total displacement and contact stress distributions along the contact line of coated members are presented.

“…Finally in order to improve the corrosive resistance of the Ti-6Al-4V a coating should be added on the surface, i.e. TiN (Liu, 2003). The problem of this approach is that sometimes the coating is not biocompatible.…”
