“…The composites show values lower than 1 µA-cm −2 , with a minimum of 0.276 µA-cm −2 for the Ti64/15Cu sample. The value obtained for Ti64 is much higher than those reported for additively manufactured Ti64 (0.008 µA-cm −2 ) under Hank's solution [45], which is probably due to the high porosity of the sample sintered at 1100 • C. However, the values obtained for the Ti64/xCu samples are lower than those reported for Ti-Cu alloys fabricated by melting [45][46][47] under Hank's solution or by sintering under NaCl [13], in spite of the remaining porosity. I corr is linked to the corrosion rate (V corr ) by means of Faraday's law [47]:…”

Ti6Al4V (Ti64) alloy is the most used metal material for bone implants because of its good biocompatibility and adapted mechanical properties. Nevertheless, it shows low antibacterial activity, which may favor its failure. Addition of antibacterial elements such as copper should avoid this drawback. This work studies the addition of Cu into a Ti64 matrix resulting in Ti64/xCu composites. Powder mixtures of Ti64/xCu were compacted in a die and then sintered at 1100 °C. Sintering kinetics indicate that densification is achieved by pore filling due to eutectic liquid formed by the reaction of Ti and Cu. The microstructure of the sintered samples is composed mainly of α-Ti and Ti2Cu phases, but TixCuy intermetallics were also found. Microhardness is increased by the addition of Cu due to densification and the formation of harder phases such as Ti2Cu. However, the stiffness and compression strength are barely the same for all composites. The corrosion resistance is significantly improved by the addition of Cu. Finally, the material with 15 wt% of copper showed the best compromise.

“…Peri-implant diseases, such as peri-implant mucositis or periimplantitis, can occur as a result of the formation and maturation of biofilms on the surfaces of dental implant materials. These diseases can have a negative impact on the long-term success of teeth implants [3,4]. Therefore, bacteria should be effectively killed, and the formation of biofilms on the surfaces of implants should be discouraged to avoid implants from failing due to bacterial infection and prevent further infections from occurring [5][6][7].…”

The composition of the phases and the microscopic structure of Ti-X% Cu (0, 0.5, 2.5, 5)% prepared alloys was investigated by scanning electron microscope (SEM), and the antibacterial activity was assessed to investigate the effect of the Cu content on the antibacterial activity with or without coating with sliver nanoparticles and graphene nanosheets. The alloys were coated using pulse laser deposition. The alloys of Ti-X%Cu were prepared by the metallurgy process. Finally, the thermal conductivity was studied to determine the effect of increasing the copper content and the coating with nanoparticles. Electron microscopy (SEM) of the alloys before coating showed that the pure titanium is homogeneously distributed and the (Ti-0.5%Cu, Ti-2.5%Cu, and Ti-5%Cu) there are precipitates of (200–800) nm while in scanning electron microscopy (SEM) images of the coated alloys the silver nanoparticles were distributed (20- 26) nm, and graphene oxide was found to be less than (100) nm. The rate of inhibition of bacterial growth increases with increasing concentration copper and with the presence of coatings, and the best inhibition ratio for the sample was (Ti-5%Cu with AgNPs/rGONPs). On the other hand, thermal conductivity of the alloys after coating is less than it was in the uncoated alloys.

“…Therefore, the engineering of nanostructured thin films based on Ti and Cu materials brings the possibility to reach sensors with multifunctional features, where resistance to corrosion, thermoresistivity response, and biocompatibility are present [ 21 , 22 ]. The combination of a thermal functionalized with antimicrobial characteristics can open interesting solutions for high-traffic surfaces [ 23 , 24 , 25 , 26 ].…”

Titanium-copper alloy films with stoichiometry given by Ti1−xCux were produced by magnetron co-sputtering technique and analyzed in order to explore the suitability of the films to be applied as resistive temperature sensors with antimicrobial properties. For that, the copper (Cu) amount in the films was varied by applying different DC currents to the source during the deposition in order to change the Cu concentration. As a result, the samples showed excellent thermoresistivity linearity and stability for temperatures in the range between room temperature to 110 °C. The sample concentration of Ti0.70Cu0.30 has better characteristics to act as RTD, especially the αTCR of 1990 ×10−6°C−1. The antimicrobial properties of the Ti1−xCux films were analyzed by exposing the films to the bacterias S. aureus and E. coli, and comparing them with bare Ti and Cu films that underwent the same protocol. The Ti1−xCux thin films showed bactericidal effects, by log10 reduction for both bacteria, irrespective of the Cu concentrations. As a test of concept, the selected sample was subjected to 160 h reacting to variations in ambient temperature, presenting results similar to a commercial temperature sensor. Therefore, these Ti1−xCux thin films become excellent antimicrobial candidates to act as temperature sensors in advanced coating systems.
