제목 | Friction and Wear Properties of Ni/Sn Electroplated Films Changed Surface Profile |
초록 | In recent years, the vehicles have been electronic for safety function, environmental performance, and improving the comfort. As the results electrical connection component have been increasing. There is an increasing demand for low insertion force of the in-vehicle connector because of manual engage such as ECU (Electronic Control Unit) connector. In this study, influence of properties as connecter terminal for the in-vehicle was investigated in changing surface shape with laser irradiation because the laser makes it easy to change the shape. The samples were subjected to laser irradiation and formed Ni / Sn electroplating. The indenters were also treated with same metal films on copper alloy to obtain friction characteristics in the same material. In addition, the samples were prepared that changed width and depth of the concave with laser process. The friction coefficient of the samples was measured under various conditions and compared with smooth surface. In case of indenter was sliding parallel to the concave direction, the friction coefficient was decreased about 50% at the maximum compare with smooth surface. The friction coefficient of the other angle sliding was decreased as same as parallel sliding. However the friction coefficient of parallel sliding was lowest value. In case of changing indenter load, the friction coefficient of samples formed concave was decrease compare with smooth surface. In addition contact resistance of the concave samples also decrease compare with smooth surface. |
