 The study aimed to improve the corrosion behavior of milligram ul alloys in also pedic applications by introducing cow via selective laser melting SLM. Results showed that cow reacted with milligram and ul, suppressing the formation of coarse milligram 17 ul 12 phase and promoting the formation of milligram ul 2ca phase. The rapid solidification during SLM promoted homogeneous precipitation of the second phase, which effectively protected milligram grains from corrosion solution invasion. As a result, the degradation rate was reduced from 0.073 to 0.031 milligram cm2h1 and az61-9 cow exhibited good cytocompatibility, making it a promising candidate for orthopedic implants.
