摘要：

The fabrication of bone screws by non-cutting technology was first developed in this study. The relationship between microstructure and mechanical properties of bone screws were studied by metallographic observation, SEM, microhardness test, thread pull-out and breakaway torque tests. The results show that the deformation area of bone screws by non-cutting is 150 μm in thickness. The deformation rate decreases gradually from the surface to the center of bone screws. The mechanical properties of bone screws fabricated by non-cutting technology are superior to those of bone screws which are made by cutting process. ©, 2015, Rare Metals Materials and Engineering Press.
