During the past decades, several works have been reported on the study of nanomaterials due to their potential applications (energy storage, environment, solar cells, aerospace, food, cancer therapy, etc). Among these nanomaterials we can site titanium-based alloys which are mainly applied in the biomedical and dental fields. These materials have interesting properties, when compared with stainless steel and Co-based alloys, such as high corrosion resistance, high biocompatibility; relative low modulus; good fatigue strength, low densities, which give high specific strength. The limitation of Ti-based alloys is their poor wear and tribological behavior that requires improvement.
