摘要：

Abstract In this work, porous Ti‐15Mo scaffolds with different porosity gradient structures (uniform gradient structures [U‐BCC], level gradient structures [LG‐BCC], and vertical gradient structures [VG‐BCC]) were fabricated by selective laser melting, and the corrosion fatigue testing in Hank's solution was conducted for the first time. The fatigue strength order, when considering the same fatigue life, follows the sequence of LG‐BCC structure > U‐BCC structure > VG‐BCC structure. Cyclic ratcheting is a prominent factor leading to f...
