“…Overall, it is assumed that materials better adhere to hydrophilic surfaces [46]. Moreover, lower surface energies of adhesives should allow for their better adhesion and good bonding [47]. Giving a constant surface energy of cements, their adhesion will depend on the surface energy of titanium alloy specimens.…”

Spacers, in terms of instruments used in revision surgery for the local treatment of postoperative infection, are usually made of metal rod covered by antibiotic-loaded bone cement. One of the main limitations of this temporary implant is the debonding effect of metal–bone cement interface, leading to aseptic loosening. Material selection, as well as surface treatment, should be evaluated in order to minimize the risk of fraction and improve the implant-cement fixation the appropriate manufacturing. In this study, Ti13Zr13Nb alloys that were prepared by Selective Laser Melting and surface treated were coated with bone cement loaded with either gentamicin or nanosilver, and the effects of such alloy modifications were investigated. The SLM-made specimens of Ti13Zr13Nb were surface treated by sandblasting, etching, or grounding. For each treatment, Scanning Electron Microscope (SEM), contact profilometer, optical tensiometer, and nano-test technique carried out microstructure characterization and surface analysis. The three types of bone cement i.e., pure, containing gentamicin and doped with nanosilver were applied to alloy surfaces and assessed for cement cohesion and its adhesion to the surface by nanoscratch test and pull-off. Next, the inhibition of bacterial growth and cytocompatibility of specimens were investigated by the Bauer-Kirby test and MTS assay respectively. The results of each test were compared to the two control groups, consisting of commercially available Ti13Zr13Nb and untreated SLM-made specimens. The highest adhesion bone cement to the titanium alloy was obtained for specimens with high nanohardness and roughness. However, no explicit relation of adhesion strength with wettability and surface energy of alloy was observed. Sandblasting or etching were the best alloys treatments in terms of the adhesion of either pure or modified bone cements. Antibacterial additives for bone cement affected its properties. Gentamicin and nanosilver allowed for adequate anti-bacterial protection while maintaining the overall biocompatibility of obtained spacers. However, they had different effects on the cement’s adhesive capacity or its own cohesion. Furthermore, the addition of silver nanoparticles improved the nanomechanical properties of bone cements. Surface treatment and method of fabrication of titanium affected surface parameters that had a significant impact on cement-titanium fixation.

“…Surface free energy of textured surfaces was calculated by equations derived for the square roots of dispersive (g d s ) 0.5 and polar (g p s ) 0.5 components. 32 The highly-hydrophilic stainless steel exhibited highest values of polar component (g p s ) 0.5 ¼ 6.1 (mJ m À2 ) 0.5 while dispersive component had values of (g d s ) 0.5 ¼ 5.2-5.3 (mJ m À2 ) 0.5 for all surfaces from highly-hydrophilic to super-hydrophobic. The polar component (g p s ) 0.5 decreased gradually with the change of the surface structure and formation of ripples and nanospikes until the point, where superhydrophobic surface had negative values of polar component (g p s ) 0.5 < 0 (mJ m À2 ).…”

“…On the other hand, an excess in this roughness can be negative. If the cavities generated are very high, the penetration capacity of the adhesive decreases, generating a worse bonding quality due to the formation of localized stress concentration [27]. To achieve this, different technologies have been studied nowadays, the most interesting being shot blasting and laser surface texturing.…”

Surface modification by different technologies prior to joining operations or improving tribological properties is a point of great interest. Improving surface activation by increasing the roughness of the metal is a relationship that is becoming more defined. In turn, an increase in surface wettability by evaluating contact angles indicates surface activation by obtaining a high surface free energy. Technologies such as shot blasting and laser surface texturing (LST) have generated several scientific studies where they have identified the influence of parameters on the formation of rough surfaces with defined patterns. However, the application of abrasive water jet texturing (AWJT) has been little studied as an alternative. This article compares these technologies in the texturing of a carbon steel s275 in order to identify the relationship between surface quality and surface activation. It has been determined that AWJT produces the highest Rt values close to 64 µm with a cross feed of 0.45 mm and a traverse speed of 5000 mm/min. Furthermore, LST obtains the best values of free surface energy by combining a power of 20 W with a frequency of 20 kHz and a sweeping speed of 10 mm/s. Finally, contour diagrams have been obtained which relate these variables to the texturing parameters.
