Resumo(s): | The development of new multifunctional coatings to apply on medical biomaterials continues to be required, since materials commonly used in hip prostheses still presenting failures. Multifunctionality is the result of a synergy, on the nanoscale level, of good corrosion, mechanical and tribological properties. Additionally, a biomaterial must always be biocompatible. Besides these properties, the major challenge would be to get a material that also has antimicrobial activity. In this context, the development of advanced materials with the ability to present these properties is being regarded as a strategy to prevent the colonization of implant and biofilm formation by bacteria. So, in this review, the attention is focused on the description of the funda- mental points of the natural synovial joint, since, its mechanical and tribological characteristics are the main causes that lead to the necessity of its replacement by an implant. Moreover, a contextualization was also performed on the hip replacement surgery and the biomaterials used, with a focus on their mechanical and tribological properties. Finally, it is explained the need of surface modification and the potential of TiCN coatings doped with silver. |
