Nacre-like Co–Cr–Mo/Ti2O3 coating on the Co–Cr–Mo substrate prepared using spark plasma sintering

摘要: Abstract Despite the common use of Co–Cr–Mo based prostheses in orthopedics, wider medical applications such implants are often limited by their inherent bioinertness and inadequate adhesion to bone. A bioactive ceramic coating can improve bonding In this study, a nacre-like Co–Cr–Mo/Ti2O3 on substrate was prepared one single step using spark plasma sintering (SPS). The microstructure, mechanical properties, biocompatibility pellet were extensively studied. lamellar Ti2O3 layers with thickness several microns alternated, resembling “bricks‐and‐mortar” microstructure nacre. consisted γ phase, e phase carbide. interfacial between strong, which is essential achieving high ductility. incorporation form composite led improved biocompatibility, MG63 human osteosarcoma cells cultured surface exhibiting faster proliferation higher viability.
