In present embodiment, class bores carbon-coating 200 needs through design to meet the object of the invention, mainly considers that point has following two aspects:
Class is bored carbon-coating 200 and is comprised sp2The graphite-structure of key and sp3The diamond cubic structure of key.On the one hand, sp3The hardness of the diamond cubic structure of key is higher, and scratch resistance, wearability are preferably.But, it relatively also has higher internal stress, when class bores the sp of carbon-coating 2003When key is higher, molding can be difficult to, and bad with the adhesion of the first cover plate 11.
On the other hand, sp2The graphite-structure of key is provided that better slip, makes object bore carbon-coating 200 surface more easily in class and moves, reduces friction, promote scratch resistance, abrasion resistant effect；And sp2The graphite-structure of key has relatively low internal stress, relative better with the adhesive force of the first cover plate 11.
But for the light transmission that class bores carbon-coating 200, sp2The graphite-structure of key compares sp3The impact of the light transmission that class is bored carbon-coating 200 by the diamond cubic structure of key is bigger, specifically, sp2The content of the graphite-structure of key is more many, and the light transmission that corresponding class bores carbon-coating 200 is more poor, and sp2The content of the graphite-structure of key is more few, and the light transmission that corresponding class bores carbon-coating 200 is more good.
Therefore, considering class and bore tack and the light transmission of carbon-coating 200, in one of present invention embodiment, class bores the sp of carbon-coating 2003Linkage content is to be advisable be more than or equal to 15% and less than or equal to 30%.
Especially, present invention etc brill carbon-coating 200 is formed on the first cover plate 11 surface mainly through the mode of vacuum splashing and plating.Class bores the sp of carbon-coating 2003When linkage content is by controlling vacuum splashing and plating, hydrogen flowing quantity and the energy that dissociates control.Specifically, when hydrogen flowing quantity more than 12sccm and dissociates energy between 100～700ev, it is possible to control class and bore the sp in carbon-coating 2003Linkage content is be more than or equal to 15% and less than or equal to 30%.
