Since the presentation of the cell adhesion concept, properties of the contact surface between osteoblasts and titanium implant and possible methods to enhance related characteristics have attracted much attention in orthopedic investigations. The creation of microtextures on the titanium implant is an important method to improve cell adhesion. This research includes the employment of Ultrasonic Assisted Turning (UAT) to create special microtextures on the titanium implant. Also, the developed interfacial ratio (Sdr) are analyzed to understand the effect of main surface characteristics on the adhesion behavior and parameters. Moreover, the effects of ultrasonic vibrations on Sdr are presented by theoretical relation and graphical modeling. Results showed micro dimples (textures) depth and width were a function of ultrasonic characteristics (amplitude and direction) and cutting speed of turning. Developed interfacial ratio (Sdr) was another surface parameter that improved by UAT (about 20% in geometrical simulations) while surface roughness did not change significantly by the application of UAT. SEM images show larger integrin and extended fibronectin of osteoblast which adhered to the textured surfaces. This result demonstrated the abilities of UAT to fabricate titanium implants with enhanced adhesion properties for osteoblast cells.

“…On the other hand, austenitic stainless steel type 316L alloy provides better wear resistance than Ti6Al4V [15][16][17]. Brończyk et al [15] worked on the tribo-corrosion behaviour of Ti6Al4V, and AISI 316L simulated in normal and inflammatory conditions.…”

“…Therefore they recommended using 316L stainless steel alloy as an implant. In the context of joint and bone replacement which mainly depends on the stability of the mechanical fixation, Mahesh M. Sonekaret et al [16] made a comparative study on the tribological behaviour between 316L and Ti6Al4V using a wear test under different loads. The results showed better friction behaviour of AISI 316L steel.…”

This study aims to investigate the influence of adding a coating layer of austenitic stainless steel type 316L on Ti6Al4V alloy on corrosion behaviour. Samples of 316L, Ti6Al4V, and 316L on Ti6Al4V were prepared by hot-press sintering of their powders. The potentiodynamic polarization technique was used to characterize the corrosion behaviour of the samples in 0.9 and 3.5 wt. % NaCl concentrations. The corrosion potential (Ecorr.), current density (icorr) and corrosion rate (CR) of the sintered samples were compared in this study. The results showed that 316L samples had the best corrosion resistance, although micropits were observed on the surface, while Ti6Al4V samples had the lowest. This corrosion behaviour of sintered 316L samples can be interrelated to the existence of a passive layer on stainless steel alloys that can be attacked by chloride ions and causing localized corrosion. In general, the CR values of Ti6Al4V samples coated by 316L were between the 316L and Ti6Al4V samples. The CR values of the samples, in 0.9 wt. % NaCl, did not show significant changes with increasing time, as the CR for 316L values were around 0.003 mm/year, while for Ti6Al4V the CR values changed noticeably from 0.018 mm/year of 0 hr, to 0.015 mm/year for 24 hours. However, the changes were less than that of Ti6Al4V. For 3.5 wt. % NaCl solution, although the same order of CR remained, i.e., the CR values of coated Ti6Al4V samples were between 316L (lowest) and Ti6Al4V (highest), the overall CR values for the samples were higher than 0.9 wt. % NaCl.
