| 摘 要： | 为提高汽车用灰铸铁制动毂的耐磨性和使用寿命,运用仿生耦合原理,采用激光雕刻技术在灰铸铁表面加工出点状、条纹状和网格状的非光滑单元体。研究了单元体的显微组织,不同激光加工能量、不同单元体形态的仿生非光滑试样的摩擦磨损性能,以及仿生耦合制动毂在实际工况条件下的使用情况。试验结果表明:仿生耦合制动毂具有优良的耐磨性和较高的摩擦系数,在实际工况下比普通制动毂寿命提高50%以上。

| Abstract: | To improve the wear resistance and prolong the service life of gray cast iron brake drums, three types of bionic non-smooth units, i.e. spotted units, striated units and latticed units were formed on the surfaces of gray cast iron by bionic coupling laser processing with different amount of laser energy. The microstructure of the bionic unit was examined and the friction and wear behaviors of bionic coupling brake drums were investigated. The results indicate that bionic coupling brake drums had good wear resistance and high friction coefficient. The service life of bionic coupling brake drums were improved by 50% upward compared with normal drums. |
