Abstract

In order to acquire medical implants with excellent performance, research needs to be conducted on the performance of selective laser manufacturing parts after heat treatment. Tensile testing machine and impact testing machine were adopted to carry out tensile and impact experiments respectively to the manufacturing parts. Metalloscope and SEM were used to observe the surface topography and study its fracture mechanism. The results show that the untreated manufacturing parts built by SLM have high strength of extension. SLM manufacturing CoCrMo alloy has higher ductility under cold condition in 1 200℃ annealing furnace. The hardness decreases with the temperature increase of heat treatment. There is a U-shaped relationship between the impact energy and heat treatment temperature. With the increase of heat treatment temperature, crystal grain of SLM manufacturing parts become bigger gradually and the internal stress reduces. The fracture mechanism under the condition of 1 200℃ annealing is ductile fracture, which provides the basis for the application of SLM CoCrMo alloy in the medical implants.
