2、擦系数均不断下降,GLC/GCr15 体系的比磨损率大体上呈下降趋势;GLC/Si3N4、GLC/Al2O3体系的比磨损率则不断增大。关键词:GLC 薄膜,速度,载荷,摩擦,磨损河南科技大学毕业论文-化工 071 王艳IIEFFECT OF COUNTERPART MATERIALS ON TRIBOLOGICAL PROPERTIES OF H-FREE GLC FILMSABSTRACTH-free GLC films were prepared by using an unbalanced magnetron sputtering deposition method.

3、f counterpart materials on tribological properties of GLCs were examined on a rotation-type ball-on-disc tribometer. After the tests, the wear tracks and debris were observed using a scanning electron microscope. In addition, a non-contact three-dimensional surface profiler was employed to measure t
4、he depth and width of wear tracks and to calculate the specific wear rate. The major results are shown as below: 1. As the sliding speed increases under a constant load, the friction coefficient generally decreases, but the wear rate first increases and then decreases for the GLC/GCr15 system. While
5、 for the GLC/Si3N4 and GLC/Al2O3 systems, both the friction coefficient and wear rate increase generally. 2. As the load increases at a constant sliding speed, the three systems commonly display a reduction in friction coefficient. But the wear rate does not change consistently. It decreases for the
