Embodiment Construction
[0018] The specific embodiment of the present invention will be further described below in conjunction with an embodiment, but the content of the invention is not limited thereto.
[0019] 1) Mix 1 gram of graphene and 100 grams of Mg-Zn alloy powder in pure alcohol, then perform ultrasonic treatment, the ultrasonic power is 250w, the ultrasonic time is 10min, then filter and dry in a drying oven for 20h;
[0020] 2) The mixed powder obtained in step 1 is ball milled for 8 hours at a speed of 300 r / min under an argon protective atmosphere to obtain a composite powder of graphene and Mg-Zn;
[0021] 3) The composite powder obtained in step 2 is carried out under the conditions of a selective laser process with a laser spot diameter of 0.1mm, a powder coating thickness of 0.2mm, a laser power of 35W, and a scanning speed of 150mm / min under an argon protective atmosphere. Selective melting is to obtain magnesium alloy artificial bone reduced and enhanced by graphene.
