Abstract
The present invention relates to a method for growing a diamond film tube through a uniform thermal field array. The present invention is characterized in that in a container which is filled with carbonaceous gas compounds, etc., electric heating wires with opposite arc openings and in circular arc shape are arranged vertically through an electric heating wire rack, and a plurality of film tube growing wires are vertically arranged between two electric heating wire arrays which are opposite at the arc openings through the wire rack. The one-time operation flow of the method can be used for producing a plurality of diamond film tubes with different length, different internal diameters and uniform tube wall thickness, and the production cost can be reduced.
Description
The present invention relates to the chemical vapour deposition of carbon.
Diamond film tubes has broad application prospects in fields such as industry and science and technology, but at present it is made the laboratory development state that only is in.Thereby now external having with heated filament decomposition hydrocarbon polymer makes carbon center on the report that one metal wire deposition makes the diamond film tubes method.Its method is once manufactured operating process only can make a diamond film tubes, and also there is the shortcoming of thickness of pipe inequality in the film pipe.
The purpose of this invention is to provide a kind of operating process of once manufacturing and to produce many diamond film tubes methods.
Technical solution of the present invention is: it is in being filled with gas containers such as carbonaceous gas compound, make nichrome wire be the relative circular arc of nock by the electric heating guide frame and erect arrangement, and film pipe growing filament vertically is arranged between the two relative electrothermal filament rows of nock by guide frame.
Technique effect of the present invention is: this method once manufacture operating process can produce many different in size, internal diameter is different, the uniform diamond film tubes of thickness of pipe can reduce production costs greatly.
Accompanying drawing is embodiment of the invention nichrome wire and film pipe growing filament distribution plan.
Embodiment: as shown in the figure, it is in being filled with gas containers such as carbonaceous gas compound 1, make nichrome wire 3 be the relative circular arc of nock by electric heating guide frame 2 and erect arrangement, and many film pipe growing filaments 4 vertically are arranged between the two relative electrothermal filament rows of nock by guide frame 5.
