与致密金属多孔金属相比,泡沫钛合金孔隙率可调,强度、刚度等与植入部位的骨骼更加匹配,可以减少“应力屏蔽”现象,因而近年来在医用方面引起了广泛的关注。剧烈的运动会使人体承力的骨和关节(如髋、膝关节等)产生断裂或微裂纹,这往往由疲劳载荷导致。 Compared with the dense metal porous metal, the foam titanium alloy porosity is adjustable, the strength, stiffness and other parts of the bone more closely match the implant can reduce the “stress shielding ” phenomenon, which in recent years has caused widespread medical attention . Severe exercise can cause fractures or microcracks in the bones and joints (such as hips, knees, etc.) that are the body’s bearings, often caused by fatigue loads.
