Embodiment of the present invention 5-6 for preparation described in embodiment 4, has just changed the concentration of surfactivity sulphur by above.In embodiment 5, there is the surfactivity sulphur (the ADDITIN RC2540 of 1wt%) (solid line in Figure 10) of 3.6wt%, and in embodiment 6, have the surfactivity sulphur (the ADDITIN RC2540 of 0.5wt%) (dotted line in Figure 10) of 1.8wt%.
Comparative example 6 and 7 is also pressed embodiment 4 preparations, just applies the surfactivity sulphur of lower concentration.Particularly, the surfactivity sulphur (the ADDITIN RC2540 of 0.1wt%) that the surfactivity sulphur (the ADDITIN RC2540 of 0.25wt%) that comparative example 6 (thick dashed line in Figure 10) comprises 0.9wt% and comparative example 7 (dotted line in Figure 10) comprise 0.36wt%.
Figure 10 has described the profile measurement result after wear testing.Can find out, the ADDITIN RC2540 of the 0.5wt% of minimum quantity is significant quantity.In contrast, the ADDITIN RC2540 of lower concentration does not have resultfully, this means that surpassing 10%DLC coat-thickness will be removed.Even if but under the ADDITIN of minimum concentration RC2540, all DLC coating is all removed.
Embodiment 7-8 and comparative example 8
Embodiment of the present invention 7-8 with by above for preparation described in embodiment 3, just changed the concentration of surfactivity sulphur.In embodiment 7, there is the surfactivity sulphur (the ADDITIN RC2515 of 1wt%) (solid line in Figure 11) of 0.4wt%, and in embodiment 8, have the surfactivity sulphur (the ADDITIN RC2515 of 0.5wt%) (dotted line in Figure 11) of 0.2wt%.
Comparative example 8 is also pressed embodiment 3 preparations, just applies the surfactivity sulphur of lower concentration.Particularly, the surfactivity sulphur (the ADDITIN RC2515 of 0.1wt%) that comparative example 8 (dotted line in Figure 11) comprises 0.04wt%.
Figure 11 has described the profile measurement result after wear testing.Can find out, the ADDITIN RC2515 of the 0.5wt% of minimum quantity is significant quantity.In contrast, low concentration be the ADDITIN RC2515 of 0.1wt% be do not have resultful.Even if but under the ADDITINRC2515 of minimum concentration, all DLC coating is all removed.
Have under the condition that does not depart from spirit of the present invention and essential attributes thereof, the present invention can be other form, therefore, when representing the scope of the invention, should be with reference to claims rather than aforementioned specification.
