Abstract
The invention discloses a kind of preparation method of hard valve connections, comprise the following steps；1）Selection, the selection trade mark is the hard alloy wolfram steel of YL10 series；2）Blank is processed；3）Rough valve connections surface be ground, polished, be cleaned by ultrasonic, dried；4）Valve connections are put into vacuum chamber, treat that vacuum reaches 6 × 103After Pa, argon gas to 2Pa, plus DC negative bias voltage are passed through to 150V, aura cleaning 10min is carried out to sample；Subsequently into film deposition process；5）Hard valve connections are obtained after completing thin film deposition.There is the hard valve connections that a kind of preparation method of hard valve connections of the present invention is made hardness higher to be hardly damaged, it is adaptable to relatively more severe external environment condition, with certain anticorrosive, performance of high temperature resistance.
Description
Technical field
The present invention relates to a kind of preparation method of hard valve connections.
Background technology
Metal valve connector is applied on valving, is easily scratched in use, is damaged, so as to influence it
Service life.
The content of the invention
It is an object of the invention to provide a kind of preparation method of hard valve connections, it is intended to solve the above problems.
To achieve these goals, the technical scheme is that designing a kind of preparation method of hard valve connections,
Comprise the following steps；
1）Selection, the selection trade mark is the hard alloy wolfram steel of YL10 series as the turned blank of valve connections；
2）Blank is processed, and the blank to choosing carries out peripheral milling, drilling, inner circle mill, mills out internal thread, obtains rough valve and connect
Part；
3）Rough valve connections surface be ground, polished, be cleaned by ultrasonic, dried, obtaining valve connections；
4）Valve connections are put into vacuum chamber, treat that vacuum reaches 6 × 103After Pa, argon gas to 2Pa is passed through, plus direct current is born
- 150V is biased into, aura cleaning 10min is carried out to sample；Subsequently into film deposition process；Technological parameter is：Target-substrate distance is
30mm, C2H2Partial pressure progressively increases to 0.3Pa from 0.003Pa, target current 0.3A, and pulsed bias are -30V, dutycycle 25%,
300 DEG C of depositing temperature, total sedimentation time 1.5h；
5）Complete to close target power supply switch after thin film deposition, stop the supple of gas or steam, continue to vacuumize, temperature is reduced to room temperature, bleeds off vacuum, takes
Go out hard valve connections.
Preferably, the hard alloy wolfram steel trade mark is YL10.1.
The advantages of the present invention are：A kind of preparation method of hard valve connections of the present invention, this method
There is the hard valve connections being made hardness higher to be hardly damaged, it is adaptable to relatively more severe external environment condition, with certain
Anticorrosive, the performance of high temperature resistance.
Specific embodiment
With reference to embodiment, specific embodiment of the invention is further described.Following examples are only used for more
Plus technical scheme is clearly demonstrated, and can not be limited the scope of the invention with this.
Embodiment：

2）Blank is processed, and the blank to choosing carries out peripheral milling, drilling, inner circle mill, mills out internal thread, obtains rough valve and connect
Part；
3）Rough valve connections surface be ground, polished, be cleaned by ultrasonic, dried, obtaining valve connections；
4）Valve connections are put into vacuum chamber, treat that vacuum reaches 6 × 103After Pa, argon gas to 2Pa is passed through, plus direct current is born
- 150V is biased into, aura cleaning 10min is carried out to sample；Subsequently into film deposition process；Technological parameter is：Target-substrate distance is
30mm, C2H2Partial pressure progressively increases to 0.3Pa from 0.003Pa, target current 0.3A, and pulsed bias are -30V, dutycycle 25%,
300 DEG C of depositing temperature, total sedimentation time 1.5h；
5）Complete to close target power supply switch after thin film deposition, stop the supple of gas or steam, continue to vacuumize, temperature is reduced to room temperature, bleeds off vacuum, takes
Go out hard valve connections.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, on the premise of the technology of the present invention principle is not departed from, some improvements and modifications can also be made, these improvements and modifications
Also should be regarded as protection scope of the present invention.
