温度对生物关节替代材料摩擦性能的影响研究
摘要本次设计题目温度对生物关节替代材料摩擦性能的影响研究。 人工关节摩擦学研究属于生物摩擦学范畴，对关节外科临床工作具有重要指导意义。
由于人体内运动的载荷是周期变化的，因此在植入的人工关节假体各部件之间的接触表面 会发生各种形式的摩擦运动，例如扭动、滑动或者微动。这些不同载荷、速度、位移等情 况下的微动或扭动持续作用下在假体界面会产生一定的摩擦热，以此带来温度的变化可能 会对假体的摩擦学性能比如摩擦系数，表面粗糙度等，以及腐蚀情况造成一定的影响，这 些消极的影响可能会让植入的关节假体在这样长期的作用下慢慢失效，这些植入物产生的 磨屑磨粒等可能溶解在关节液力，对人体健康造成威胁。因此，研究人工关节植入物接触 界面间的温度即摩擦热的产生对其植入材料的力学特征、摩擦特性的影响具有重要意义。72689

Effect of temperature on he tribological properties of biological joint replacement material
Abstract The title of this project is effect of temperature on he tribological properties of biological joint replacement material。
The tribology of artificial joint belongs to the field of bio tribology, which has important guiding significance to the clinical work of joint surgery。 Because the load of the movement of the human body is periodic, so the contact surface between the various components of the implanted artificial joint prosthesis will occur in various forms of friction motion, such as twisting, sliding or fretting。These different load, velocity, displacement and other conditions of the micro motion or torsional under the continuous action of the prosthesis interface will produce a certain friction heat, In order to bring the temperature changes may be the prosthesis of the friction coefficient, surface roughness, etc。, as well as the corrosion situation caused some impact, These negative effects may allow the implantation of the joint prosthesis in such a long-term effect of slowly failure, these implants produced wear debris may dissolve in the joint fluid, pose a threat to human health。Therefore, it is significant to study the influence of temperature on the friction characteristics of the interface between artificial joints。
