Specific embodiment
Referring to Fig. 1 to Fig. 5, the present invention is described in detail.
A kind of not Sang Shi ornaments, Sang Shi jewelry surface is not coated with diamond film.By taking Mo Sang is bored as an example, referring to Fig.1, the Buddha's warrior attendant
The not mulberry of stone membrane coat bores the pattern observed of the sample surfaces under AFM (atomic force microscope), and coating structure is fine and close, equal
Even, average grain size is 100nm-200nm or so.
Referring to Fig. 2, it is seen that be located at 1331cm-1Diamond Raman (Raman) characteristic peak.Positioned at 1120cm-1Neighbouring dissipates
Unrestrained peak is related with the grain size of diamond film, is a very tiny presentation of crystal grain.It is shown in the appearance at this peak and Fig. 1 micro-
Little crystal grain is consistent.
Referring to Fig. 3, Fig. 4, in the not Sang Shi ornaments for having diamond film to surface and not no not Sang Shi ornaments of diamond film
When carrying out the experiment of anti-diamond pressing delineation ability under the normal pressure of maximum 20N, in scoring process, normal pressure is (real by zero
Pretightning force is 0.02N on border) it is gradually increased to 20N, during this period in (1 minute), the distance streaked is 2mm.
Wherein, the not Sang Shi ornaments of diamond film do not occur about (to amplify from optical microscopy in 8N or more
Multiple 100) photo is clearly visible scratch, and a series of lateral sharp cracks occurs, and under equal conditions, there is diamond film on surface
Not Sang Shi ornaments there is no obvious scratch.For the not Sang Shi ornaments that there is diamond film on surface, close to maximum pressure (20N)
Shi Caicong optical microscopy (amplification factor 200) photo can be seen that diamond film just by pressure break, the mark of brittle fracture occurs
As breach is very smooth, and as being cut knife, and film opens, and rolls.Therefore, can be illustrated by experiment, surface has diamond
The not Sang Shi ornaments of film are substantially at pressure sufficiently large (close to 20N) just by pressure break.Compared to the decorations of no plating diamond film
For product, adhesion strength is greatly improved.
The method in not Sang Shi jewelry surface plating diamond film is illustrated below.
This method comprises the following steps：Step 1：Ultrasound is carried out to not Sang Shi ornaments in Nano diamond powder suspension
Grinding pretreatment.Wherein, in Nano diamond powder suspension the granularity of Nano diamond powder in 5nm-200nm, nanogold
The concentration of Nano diamond powder is 5%-20% in hard rock powder suspension, and the ultrasonic grinding pretreated time is 2h-6h.It should
The purpose of step mainly for improve diamond film deposition Enhancing Nucleation Density so that the Enhancing Nucleation Density of diamond film be greater than 1010cm-2。
After ultrasonic grinding pre-processes, in step 2：It will Sang Shi ornaments not taken from Nano diamond powder suspension
Out, it and is cleaned, wherein cleaning is successively cleaned by ultrasonic using deionized water and dehydrated alcohol, is dried up through cold wind.
Not Sang Shi ornaments after ultrasonic grinding pre-processes and cleans, in step 3：It will the indentation of Sang Shi ornaments not set in advance
It is kept in fixed conformal sample stage.Wherein, by taking Mo Sang is bored as an example, in order to keep not, mulberry brill can be in conformal sample stage referring to Fig. 5
In be provided with recess portion 111 for keeping not Sang Shi ornaments, which is in back taper, and the depth H of recess portion 111 is about
It is the 4/5 of not mulberry drilling depth, substantially 96 ° of the cone angle R of back taper, can permit 0 ° -- 2 ° of error, for the ease of Mo Sang brill
The material of indentation, conformal sample stage is slightly softer using fine copper or graphite etc. and has the material of good thermal conductivity.Mo Sang
Boring can be pressed into the recess portion of conformal sample stage by applying the pressure of 50Kgf-250Kgf.
It is pre-processed by ultrasonic grinding, and after not mulberry bored being pressed into the recess portion of conformal sample stage, it in step 4, will not mulberry
Drill ornaments are placed in diamond film deposition furnace together together with conformal sample stage and carry out corona treatment.In step 4, direct current
Arc-plasma sprays (DC Arc Plasma Jet) CVD, and microwave plasma sprays CVD (MWCVD) and HF CVD
(HFCVD) diamond film coating that diamond film depositions method is used equally for Mo Sang to bore such as.But HF CVD is living due to gas
Change degree is not high, causes atomic hydrogen concn too low, for the diamond film coating layer ratio for figuring for having favorable optical performance
It is more difficult.Therefore, in step 4, corona treatment is sprayed using Dc arc plasma jet CVD or microwave plasma.
The temperature of corona treatment is 700 DEG C -1000 DEG C, and the time of corona treatment is 5min-30min.Appointed with completely removing
What remains in organic root ball (from Nano diamond powder suspension) on Mo Sang brill surface to deposition of diamond thin films
It influences, and activates the surface state that not mulberry bores sample, conducive to the uniform deposition of diamond film and the adhesive force of raising diamond film.
After completing corona treatment, in steps of 5：It is passed through methane, carries out diamond film deposition in situ immediately.In the step
In rapid, the concentration of methane is 0.5%-10%, and the surface temperature that Mo Sang is bored is 700 DEG C -1000 DEG C, and the pressure of cvd furnace is set as
3kPa-20kPa, sedimentation time 5min-120min.
It is 10 minutes cooling after the completion of deposition, that is, it can be taken off the sample that the not mulberry of plated film is bored.
The example for the diamond film plated film for taking the not mulberry that diameter is 6.5mm to bore (1 carat) further below is illustrated.
Sample ultrasonic grinding 3h in 30nm diamond dust suspension will not bored by mulberry first.
Sample taking-up will not bored by mulberry, cleaned up.
In 150kg power indentation height is 30mm, prefabricated back taper is cheated on the conformal sample stage surface of copper that diameter is 50mm
(95 ° of cone angle).
It will mulberry brill sample not be put into dc arc plasma CVD diamond film deposition furnace, in argon/hydrogen plasma
Handle 5 minutes (Ar：3slm；H2:8slm；Chamber pressure：3-6kPa；Plasma torch electric current：190A；Voltage：97V).Then to etc.
It is passed through methane in gas ions, flow 50sccm-240sccm, 700 DEG C -1000 DEG C of sample surface temperature, time 5min-
30min.Electric current is cut off, diamond film deposition is stopped, the cooling not mulberry that can be taken off plated film after ten minutes bores sample.
The not mulberry of the sample and non-coating that are bored by the not mulberry for being coated with diamond film coating layer that this method obtains is bored outer
Sight is compared, and can not see that diamond film coating has an impact to the optical property (heat color) that not mulberry is bored.In addition, the diamond film applies
The not mulberry of layer bores the pattern observed of the sample surfaces under AFM (atomic force microscope), and coating structure is fine and close, uniform, average
Crystallite dimension is 100nm-200nm or so.
The above description is only an embodiment of the present invention, not limits the scope of the invention, all to be said using the present invention
The equivalent structure or equivalent process transformation that bright book content is done, are directly or indirectly used in other correlative technology fields,
It should be included in scope of patent protection of the invention.
