“…Interrelations among those factors are complex and make it difficult to choose proper mechanical and physicochemical properties of a metal biomaterial. Such properties also need to comply with the surgical technique, often involving preoperative modeling of the implants [1,2].…”

EvaluatIoN of corrosIoN rEsIstaNcE of tItaNIuM alloys usEd for MEdIcal IMplaNtsThe study presents the results of investigations of modeling the usable properties of implant surfaces made of Ti6Al7Nb alloy, using the example of a dynamic hip screw (DHS) applied in surgical treatment of intertrochanteric femoral neck fractures. Numerical simulation has been performed for the model load of femoral fixation with DHS screw. The load simulation results provided the basis to select mechanical properties of the fixator elements and to define those fixation areas which are mostly susceptible to development of corrosion. The surfaces of Ti6Al7Nb alloy were ground, vibro-abrasive machined, mechanically polished, sandblasted, anode oxidized at different voltage values and steam sterilized. Results of surface topography evaluation, resistance to pitting and crevice corrosion as well as degradation kinetics of the outer layer were presented. Usability of the formed passive layer in clinical applications was evaluated through wear and corrosion tests of the femoral fixation model. The test results proved usefulness of the proposed surface modification methods for clinical application of different size and shape implants

“…Thin layers based on TiO 2 are characterized by such properties as high transparency, stability (thermal, chemical), corrosion resistance and biocompatibility . Literature data indicates, however, a number of undefined phenomena accompanying the production of TiO 2 films using the atomic layer deposition method on the surface of metal materials . The selection of appropriate parameters for film formation and comprehensive studies showing the full characteristics of their behaviour under the conditions of implantation and prolonged contact with the tissue environment during the use of the implant are still unsolved problems.…”

Surface modification techniques play a major role in shaping the physicochemical properties of 316 LVM steel used for implants. The utilised methods of surface layer modification must ensure repeatability and uniformity of the physical and chemical properties. The structure and chemical composition of 316 LVM steel implants can be modified using various methods, among which anode oxidation and sol-gel methods are dominant. One of the more important aspects related to maintaining implants (e.g. vessel stents) is ensuring the maintenance of their geometric characteristics along their entire length, which some methods cannot guarantee. For this reason, the most appropriate technique of surface modification in this context appears to involve atomic layer deposition (ALD). Improved biocompatibility is also directly related to ensuring an appropriate set of mechanical properties for the deposited layer. Thus, the study attempted to assess the mechanical properties of the TiO 2 layers on a 316 LVM steel substrate, deposited using an atomic layer depositionbased method.Keywords: 316 LVM / TiO 2 / atomic layer deposition / scratch test / nanohardness / ellipsometry / atomic force microscopy (AFM)Oberflächenmodifizierungstechniken spielen eine wichtige Rolle bei der Gestaltung der physikalisch-chemischen Eigenschaften von 316 LVM Stahl für Implantate. Die eingesetzten Methoden der Oberflächenschichtmodifikation müssen Wiederholbarkeit und Einheitlichkeit der physikalischen und chemischen Eigenschaften sicherstellen. Die Struktur und die chemische Zusammensetzung des 316 LVM Stahlimplantats können durch verschiedene Verfahren, unter anderem durch Anodenoxidation und Sol-Gel-Verfahren, signifikant modifiziert werden. Einer der wichtigsten Aspekte zur Aufrechterhaltung der Funktionalität von Implantaten (z. B. Gefäß-prothesen) ist der Erhalt ihrer geometrischen Eigenschaften entlang der gesamten Länge, die einige der Methoden nicht garantieren können. Aus diesem Grund scheint die geeignetste Technik der Oberflächenmodifikation auf der Atomlagenabscheidung (ALD) zu basieren. Verbesserte Biokompatibilität ist auch in direktem Zusammenhang mit der Gewährleistung angemessener mechanischer Eigenschaften der abgeschiedenen Schicht zu sehen. Somit versucht diese Studie, die

The paper presents the influence of mechanical surface damage on the physicochemical properties of plates after implantation made of crnimo stainless steel, used in the treatment of anterior surface deformity of the chest. analysis of the data allowed us to investigate the effect of implant design and condition of their surface on the results of chest deformation treatment. results of electrochemical, impedance and surface wettability tests and Sem observations were compared with clinical observations. When removing the plates we found only slight inflammatory-periosteal reactions. On the basis of obtained results, it can be stated that plates, in spite of mechanical damage of the surface, were characterized by good corrosion resistance, a fact which is confirmed by the results of clinical evaluation.
