CoCrMo/Ti-6Al-4V bimetallic joints were fabricated by spark plasma sintering. Higher temperature and longer holding time reduced porosity and promoted interfacial diffusion. Two reaction layers formed, with phase transformation and TiCo₃ formation, providing insight for multi-material orthopedic implants.
