This thesis for the Production and Characterization of a Multilayer Thin Film by PVD with Antibacterial Activity for Biomedical Applications is for the Master’s Program in Nanotechnology at ITESM CEM. Millions of people use some form of implant in their bodies and infection is the most serious complication affecting to an important percentage of patients, causing postoperative prosthesis failure, chronic pain and immobility. This thesis aims to develop and characterize a multilayer thin film of CrN, ZnO and PEG on the substrate Ti6Al4V to be used in implants obtaining antibacterial activity and an improvement in the mechanical and morphological properties. For the deposition process, Reactive Magnetron Sputtering was used, and the characterization was performed using Optical Microscope, SEM, EDS, XRD, AFM, Nano-Indentation, Rockwell C test using VDI 3198 norm, Contact Angle, Tribometer and Colony Forming Units Counting. The results showed an improvement in the tribological characteristics and positive antibacterial action.
