Tohoku University Technology: Co-based Alloy Powder: T13-172
Provide alloy powder suitable for 3D additive manufacturing while maintaining the various properties of Co-Cr-Mo alloys.
Co-based alloys such as Co-Cr-Mo alloys are excellent in corrosion resistance and wear resistance, and are widely used in biomaterials, casting mold materials, and dental casting materials. Additionally, using Co-Cr-Mo alloy powder with superior corrosion and wear resistance makes it possible to manufacture implant components with complex shapes. However, Co-Cr-Mo alloys have a lower hardness than iron-based alloys, which posed a challenge for their use as general industrial products. This invention makes it possible to provide a hard Co-based alloy powder that maintains corrosion resistance and wear resistance. The invention is characterized by being based on Co-Cr-Mo-N alloys and further adding carbon. When this powder is used for additive manufacturing, a process of rapid heating, melting, and rapid cooling of the powder results in a laminate with superior properties that surpass conventional Co-based alloys, thereby opening up applications for Co-based alloys in industrial products.
