Class is bored carbon-coating 200 and is formed on the first surface 101 of transparency carrier 100.But class is bored carbon-coating 200 and is not limited to this with the position relationship of transparency carrier 100, in other embodiments, class is bored carbon-coating 200 and also can be only arranged on one or more surface of transparency carrier 100.
In the first embodiment, class is bored carbon-coating 200 needs to meet the utility model object, mainly to consider, a little have following two aspects through design:
On the one hand, class brill carbon-coating 200 comprises sp
2the graphite-structure of key and sp
3the diamond cubic structure of key.Wherein, sp
3the hardness of the diamond cubic structure of key is higher, and scratch resistance, wearing quality are better.Yet it relatively also has higher internal stress, bad with the adhesion of transparency carrier 100, so that containing sp
3it is bad that the class that key is higher is bored the adhesion effect of carbon-coating 200 on transparency carrier 100.Therefore, conventionally on transparency carrier 100, make class and bore carbon-coating 200, need separately in processing procedure, to carry out suitably adjusting to promote such to bore the adhesion of carbon-coating 200 on transparency carrier 100.For example, can select that class is bored to carbon-coating 200 makes to thinner thickness, to reach the effect of low internal stress.
On the other hand, with regard to the light transmission of class brill carbon-coating 200, sp
2the graphite-structure of key compares sp
3the diamond cubic structure of key is larger on the impact of the light transmission of class brill carbon-coating 200, is specially sp
2the content of the graphite-structure of key is more, and it is just poorer that corresponding class is bored the light transmission of carbon-coating 200, and sp
2the content of the graphite-structure of key is fewer, and the light transmission that corresponding class is bored carbon-coating 200 is just better.
Therefore, comprehensive consideration class is bored tack and the light transmission of carbon-coating 200, and in first embodiment of the utility model, the thickness of class brill carbon-coating 200 is less than or equal to 15nm, and class is bored the sp of carbon-coating 200
3linkage content is greater than sp
2linkage content, and sp
3linkage content is greater than 50%.
Especially, the utility model and so on bores carbon-coating 200 and mainly by the mode of vacuum splashing and plating, is formed on transparency carrier 100 surfaces.Class is bored the sp of carbon-coating 200
3linkage content hydrogen flowing quantity and the energy that dissociates when controlling vacuum splashing and plating are controlled.Be specially, when hydrogen flowing quantity be greater than 12sccm and the energy that dissociates between 100～700ev, class is bored the sp in carbon-coating 200
3linkage content can be greater than sp
2linkage content, and sp
3linkage content is greater than 50%.
Noticeable, except considering the light transmission and tack of compound substrate structure 10, the visual effect with regard to compound substrate structure 10 in present embodiment is further considered in addition:
Noticeable, except considering the light transmission and tack of compound substrate structure 10, the visual effect with regard to compound substrate structure 10 in present embodiment is further considered in addition:
Selecting of the thickness of class brill carbon-coating 200 is improper, easily affects the visual effect of compound substrate structure 10.Experimental results show that: in compound substrate structure 10, the thickness of class brill carbon-coating 200 is larger, and compound substrate structure 10 outward appearance flavescence phenomenons are just more obvious, are called in the industry aetiolation.The thickness that bores carbon-coating 200 when class is greater than 10nm, and this aetiolation can be discovered for human eye.And the thickness of working as class brill carbon-coating 200 is greater than 15nm, this aetiolation is high-visible, has a strong impact on the visual effect of compound substrate structure 10.
Therefore, the light transmission of comprehensive consideration compound substrate structure 10, tack, and aetiolation, in first embodiment of the utility model, the preferential thickness of class brill carbon-coating 200 is less than or equal to 10nm, more preferably between 2nm between 5nm time, compound substrate structure 10 can be got a good equilibrium point between visual effect and adhesion effect.
Hydrophobic layer 300 is arranged on class and bores on the another side of carbon-coating 200 relative these transparency carriers 100.The another side that hydrophobic layer 300 is bored carbon-coating 200 with respect to such has a contact angle, this contact angle is greater than 110 degree, therefore this side of hydrophobic layer 300 presents on the whole stronger hydrophobic property and (experimental results show that, when solid surface contact angle is greater than 90 while spending, solid surface is hydrophobic, be that liquid is not easy wetting solid, easily move in its surface).Wherein the material of this hydrophobic layer 300 be mainly selected from fluorine, nitrogen, oxygen and composition thereof one of them, in order to improve the hydrophobicity of compound substrate structure 10.
Below, hydrophobic layer 300 compound substrate structures that have the compound substrate structure 10 of hydrophobic layer 300 and do not have are carried out respectively to first group of scratch resistance, wearing quality experiment test:
Experiment condition:
Adopt the steel wool of superfinishing fineness to be coated on the friction head of 2cm*2cm, under the acting force of 70N, compound substrate structure is tested.
Experimental result:
The compound substrate structure 30 that plates hydrophobic layer 300 has better scratch resistance, wearing quality than the compound substrate structure 20 that does not plate hydrophobic layer 300.
Experimental results show that:
The mantle friction factor of compound substrate structure 10 that plates hydrophobic layer 300 is less than the mantle friction factor of compound substrate structure that does not plate hydrophobic layer 300, and compound substrate structure mantle friction factor has impact to its scratch resistance, wearing quality, be specially, compound substrate structure mantle friction factor is larger, and its scratch resistance, wearing quality are just poorer; Compound substrate structure mantle friction factor is less, and its scratch resistance, wearing quality are just better.
To sum up, hydrophobic layer 300 has increased the hydrophobicity of compound substrate structure 10 on the one hand, thereby play, prevents that body structure surface is subject to adhering to of greasy dirt or steam; Hydrophobic layer 300 has also reduced the mantle friction factor of compound substrate structure 10 on the other hand, makes compound substrate structure 10 when there is external force scraping effect, and more effective minimizing external force is to its scratch and wearing and tearing.
Especially, when in hydrophobic layer 300, the percentage composition of hydrophobicity atom is larger, the hydrophobicity of hydrophobic layer 300 is just better, and mantle friction factor is just less.Therefore, in first embodiment of the utility model, in hydrophobic layer 300, hydrophobicity atom (for example, fluorine) percentage composition is greater than 50%.
Again, in actual production process, find, in hydrophobic layer 300, carbon-fluorine bond has influence on the mantle friction factor of hydrophobic layer than regular meeting with silicon oxygen bond.
Below, the compound substrate structure 10 with the carbon-fluorine bond of different proportion and the hydrophobic layer of silicon oxygen bond 300 is carried out to second group of scratch resistance, wearing quality experiment test:
Experiment condition:
On compound substrate structure 10, placing hundred grades of non-dust cloths (non-dust cloths of hundred grades of used in dustless room), adopt the counterweight of 200g to be placed on non-dust cloth, is under 100mm/min, compound substrate structure 10 to be tested in speed.
Experimental result:
When in hydrophobic layer 300, carbon-fluorine bond and silicon oxygen bond ratio are more than or equal to 50:1, the static friction factor of hydrophobic layer 300 is less than or equal to 0.1, and between hydrophobic layer 300 and non-dust cloth, dynamic friction factor is less than or equal to 0.1.Now hydrophobic layer 300 surfaces present good smoothness, and scratch resistance, the wearing quality of compound substrate structure 10 are significantly increased.
Experimental results show that:

On the one hand, class is bored carbon-coating 200 conventionally with sp
2the graphite-structure of key and sp
3the diamond cubic structure of key is primary structure.Wherein, sp
3the hardness of the diamond cubic structure of key is higher, and scratch resistance, wearing quality are better.Yet it relatively also has higher internal stress, also bad with the adhesion of transparency carrier 100.Therefore, conventionally on transparency carrier 100, make class and bore carbon-coating 200, need separately in processing procedure, to carry out suitably adjusting to promote such to bore the adhesion of carbon-coating 200 on transparency carrier 100.For example, can select that class is bored to carbon-coating 200 makes to thinner thickness, to reach the effect of low internal stress.
On the other hand, class is bored the light transmission of carbon-coating 200 and the sp that class is bored carbon-coating 200
2the content of the graphite-structure of key is inversely proportional to, and is specially sp
2the content of the graphite-structure of key is more, and it is just poorer that corresponding class is bored the light transmission of carbon-coating 200, and sp
