摘要
以医用βTi丝、NiTi丝和不锈钢丝为对象,研究了其表面粗糙度、硬度和弹性模量与摩擦性能之间的相互关系。结果表明:表面粗糙度对摩擦力的影响最显著,并与摩擦力成正相关关系。弹性模量和硬度与摩擦力成负相关关系。通过利用函数回归拟合,建立了表面粗糙度、弹性模量和硬度与摩擦力的定量关系:f=(E-0.02649)·(H-0.07035)·(Ra0.80625),R2=0.9982。
The relationships of the surface roughness, hardness and elastic modulus to the friction properties were studied based on objects of a medical NiTi wire, a medical stainless steel wire and four medical β-Ti wires. The results show that the most significant factor on the friction resistance is the surface roughness, and the friction resistance has a positive correlation with it. However, the friction resistance has a negative correlation with elastic modulus and hardness. By the regression fitting, the quantitative relationships between the surface roughness, elastic modulus, hardness and friction resistance is established, that is f = （E -0.02649）·（H-0.07035）·（Ra0.80625）, R2 = 0.9982.
