Biocompatible Ti-based metallic glass for additive manufacturing

摘要

A biocompatible Ti-based alloy having a formula of Ti_aZr_wTa_bSi_xSn_yCo_z is disclosed, wherein a is 40-44, b is 1-5 and the sum of w, x, y, z is 55. The alloy is amorphous. The alloy is applicable to manufacturing ultrafine powder which is used for additive manufacturing. The alloy is characterized in high glass forming ability, low toxicity, and high strength, and the powder thereof has low roughness and high circularity, and is suitable for implantable medical device.
