DLC film layer preparation method.
Background technology
Currently, the DLC film layer thickness deposited on the special equipment wear-resisting spare part surface of tribological field can not be controlled accurately
System, which results in fit clearance of the friction corresponding to wear-resisting spare part between secondary to be unable to get guarantee, causes to friction
Pair carries out match grinding again, and, to ensure the gap between friction is secondary, match grinding, which is processed, to be increased needed for entire special equipment parts assembly
Time, reduce the efficiency of assembling of entire special equipment parts, affect manufacturing schedule.
Invention content
The purpose of the present invention is to provide a kind of DLC film layer preparation method accurately controlling DLC film layer thickness, this method energy
It is enough that the thickness of DLC film layer is accurately controlled, ensure the fit clearance between wear-resisting spare part friction is secondary, and no longer need into
Row match grinding manufacturing procedure, saves assembly time, improves the efficiency of assembling of special equipment parts.
To achieve the above object, present invention employs following technical schemes：
A kind of DLC film layer preparation method accurately controlling DLC film layer thickness, this approach includes the following steps：
（1）Multiple tracks cleaning is carried out to wear-resisting spare part, removes greasy dirt and surface attachments on wear-resisting spare part.
（2）Wear-resisting spare part surface oxidisation after cleaning in order to prevent, N is placed on by the wear-resisting spare part after cleaning2Atmosphere
Lower drying.
（3）Wear-resisting spare part after drying is placed in vacuum cavity, and vacuumize process is carried out to vacuum cavity, directly
Vacuum degree to vacuum cavity is higher than 1 × 10-6When mbar, DLC plated films are proceeded by.
（4）It is bombarded using Ar gas ion pair wear-resisting spare parts, further to remove wear-resisting spare part surface attachments
And activate wear-resisting spare part surface.
（5）DLC films deposited layer is carried out on the surface of wear-resisting spare part using n-hexane and tetramethylsilane.DLC film layer packet
SiC layer, SiC and C layers, C layers of trilamellar membrane layer are included, the flow and sedimentation time by controlling n-hexane and tetramethylsilane are sunk
Integrated membrane layer.
（6）After DLC films deposited layer, after progress vacuum breaker is cooled to room temperature, wear-resisting spare part is taken out, using outside micrometer
The change in size before and after its plated film is measured, obtains the thickness of DLC film layer.
Further, step（4）In, the bombardment time of Ar gas ions is 20min, flow 60mL/min.
Further, step（5）In, it is respectively 35min and 60mL/min to control the sedimentation time of n-hexane and flow；Control
The sedimentation time and flow of tetramethylsilane processed are respectively 40min and 92mL/min.
Further, step（6）In, the thickness for the DLC film layer measured is 3 μm.
By above technical scheme it is found that the present invention by it is prepared by DLC film layer the parameters such as raw material, time and flow for being into
