Embodiment
Elaborate in the face of embodiments of the invention down, present embodiment provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment being to implement under the prerequisite with technical scheme of the present invention.
Embodiment 1
As shown in Figure 1, processing graphite with milling cutter on plating CVD diamond coatings, the handle of a knife diameter is φ 4, blade is long to be 30mm, cutter 5 length overalls are 100 millimeters.The cutter 5 cooling understructures of the sandwich style that present embodiment adopted are: the copper billet size is high, wide, length is 30 * 30 * 100 millimeters; The graphite corresponding size is 30 * 20 * 100 millimeters; Thickness is that 0.4 millimeter molybdenum sheet 1 is cut into 35 * 100 millimeters; In the even hole (hole depth 40mm) of 40 φ 4.2 of ground auger at interval of cooling base, uprightly insert 40 milling cutter so that install.Molybdenum sheet 1 covers on the graphite block 2, and protection graphite is not corroded by the H atom.
The first step, place the Murakami agent to carry out ultrasonic erosion the blade of above-mentioned long handle milling cutter; The prescription of corrosive fluid (weight ratio) Tripotassium iron hexacyanide: Pottasium Hydroxide: water is 1: 1: 10, about 25 minutes of time, places the dioxysulfate aqueous solution (volume ratio 1: 10) to corrode for 30 seconds again after taking-up washes; Place diadust (20 microns of granularities) alcohol suspension sonic oscillation to handle after cleaning again 20 minutes; Clean then drying up divides 5 rows to be inserted in the cooling base of sandwich style 8 of every rows 40 milling handle; Place on the water cooling platform 4 of heated filament 5CVD reaction chamber the deposition of beginning diamond coatings.
It directly is the tantalum wire of φ 0.4 that second step, heated filament 5 adopt six pairs of lines, 35 millimeters of tantalum wire spacings, and wherein a pair of height is identical with the point of a knife of milling cutter, and another is to then low 30 millimeters.Reaction chamber vacuumizes the back and feeds reactant gases (hydrogen and acetone); The deposition of beginning CVD diamond coatings behind the adjustment chamber pressure, processing parameter is: pressure 10-25Torr, total gas flow rate 700 ml/min; Acetone/hydrogen (volume ratio) is 2%; The tantalum wire temperature is about 2100 ℃, and after depositing through 3 hours, blade place deposition obtains the diamond coatings of about 6-8 micron thick.Every revolve cutter 5 positions turn 90 degrees, carry out 3 hours depositions again, obtain the diamond coatings of about 12-16 micron thick, and can effectively guarantee coating uniformity with same processing parameter.This milling cutter is used for machining graphite, and the service life as compared carbide-tipped milling cutter improves more than 8 times, and the working accuracy and the surface smoothness of workpiece also are improved.
As shown in Figure 2, described red copper piece 3 is close to water cooling platform 4, and graphite block 2 is close to copper billet, and molybdenum sheet 1 nestles up graphite block 2, and drill bit or milling cutter are vertical to be inserted in the base of being made up of red copper, graphite and molybdenum.Because the heat conductivility of copper is fine, its thermal conductivity is 400W/mK, so the temperature of the temperature of copper billet and chill station 4 is approaching, can effectively cool off milling cutter or drill bit.When directly cooling off with copper billet, better to the cooling performance of milling cutter or drill bit so, but will cause the blade underlayer temperature low excessively.The thermal conductivity ratio copper of polycrystalline graphite hangs down an one magnitude, and under thermal equilibrium state, its temperature is high more a lot of than red copper piece 3, and is less better to the cooling performance of cutter 5, but it can play regulating effect to the underlayer temperature at blade place.In CVD diamond deposition process, generally will be between 750～950 ℃.Underlayer temperature is on the low side, and sedimentation rate is slow, and benefit is that the coating internal stress is little, and adhesive force is better; Underlayer temperature is higher, and sedimentation rate is fast, but the coating internal stress is big, the adhesive force variation.Therefore underlayer temperature has an optimum value, under certain heated filament 5 temperature, through selecting the thickness and the ratio thereof of graphite and red copper piece 3, can reach the purpose of regulating underlayer temperature, and underlayer temperature is in the only scope.On the other hand, be in the graphite under the comparatively high temps, easily by H atom institute etching, therefore need molybdenum sheet 1 to protect, because molybdenum sheet 1 is a refractory metal, the H atom can not corrode it.In the cooling base of sandwich style, red copper piece 3 is effective cooling layer like this, and graphite is the temperature regulation layer, and resistant to elevated temperatures metal molybdenum sheet 1 is a resist.
For monobloc(k)type complex shaped cutters 5 such as drill bit and milling cutters, adopt heated filament CVD method to its diamond coated film in blade place, heated filament 5 be furnished with two kinds of forms:
A pair of heated filament 5 of prior art such as Fig. 3 (a) expression and elongated milling cutter (or drill bit) parallel axes, cutter 5 is in the centre.The advantage of this method for arranging is that coating is more even along the axis direction thickness distribution; Because the blade place equates along the distance of axis each point from heated filament 5, but unsuitable batch preparations coated cutting tool 5 (between a pair of heated filament 5, generally can only place a long and thin cutter 5);
Prior art such as Fig. 3 (b) are that a pair of heated filament 5 directions and cutter 5 axis directions are perpendicular; Cutter 5 is also in the centre; Its advantage is to be fit to batch preparations (many monobloc(k)type complex shaped cutters 5 can be arranged in parallel between a pair of heated filament 5); Shortcoming be coating along the axis direction skewness, the blade place is not wait along the axis each point from the distance of heated filament 5, and is thicker near the partial coating thickness of heated filament 5.
Present embodiment such as Fig. 3 (c) show, replace original a pair of heated filament 5 with upper and lower two row heated filaments 5 up and down, and like this, it can make the diamond coatings at blade place even as far as possible along the axis direction thickness distribution, can realize batch preparations again.
Illustrate that like Fig. 4 two pairs of heated filament 5 rear knife edge place coat-thicknesses of employing are along cutter 5 axis distribution schematic diagrams; A pair of heated filament 5 was along the axially corresponding deposited coatings thickness distribution of blade above Fig. 4 curve a represented; Fig. 4 curve b representes that a pair of heated filament 5 is along the axially corresponding deposited coatings thickness distribution of blade down; Fig. 4 curve c representes the deposited coatings thickness distribution that two pairs of heated filaments, 5 acting in conjunction lower edge blades are axially corresponding, this shows, it is more uniform that curve c coat-thickness distributes along axis.After adopting up and down two row heated filaments 5; Heated filament 5 total heating powers have increased, and the temperature at blade place raises easily, but owing to adopt the cooling base of sandwich style; Cutter 5 has obtained effective cooling, and the substrate surface temperature at blade place still can remain in the suitable scope.On the other hand; The increase of heated filament 5 power, the rising of heated filament 5 temperature can effectively promote the increase of active H atomic percent; This all is very helpful to improving diamond coatings quality and sedimentation rate, and reduction coating internal stress, raising sticking power are also played an important role.
