Specific embodiment
Present embodiment the technical solution adopted is that: it is comprised the following steps:
Step 1: it is in 0.10-0.15MPa that titanium metal containment, which is placed on hydraulic pressure, water temperature is not higher than 38 degrees Celsius, puts
A length of 30 minutes when setting；
Step 2: take out titanium metal containment and consolidated mounting base in workpiece blue box, environment locating for workpiece blue box
For vacuum environment, vacuum environment pressure is -0.05Mpa；
Step 3: environment vacuum locating for workpiece blue box is evacuated to 3.0E-2Pa vacuum degree, then it is sintered, burns
Junction temperature gradually rises to 650 degrees Celsius, a length of 1.5 hours when sintering temperature gradually rises；
Step 4: environment vacuum locating for workpiece blue box is evacuated to 10pa hereinafter, protecting under being 650 degrees Celsius in sintering temperature

Step 5: environment temperature locating for workpiece blue box is down to 100 degrees Celsius hereinafter, taking out titanium metal containment.
Titanium metal containment is diameter 65mm, the monolayered vessel of high 200mm, diameter 65mm, high 200mm in the step 1
Double container.Reasonably titanium metal containment is size, thickness can be improved the effect of metallographic structure.
Hydraulic pressure is 0.12MPa in the step 1, and water temperature is 25 degrees Celsius.Titanium metal containment can be played pre- well
Treatment effect.
Protective gas is persistently filled with during keeping the temperature in the step 4.Play the role of protection.
Environment temperature locating for workpiece blue box is down to 50 degree degrees Celsius in the step 5.
The working principle of the invention: it is in 0.10-0.15MPa that titanium metal containment, which is placed on hydraulic pressure, and water temperature is not higher than
38 degrees Celsius, when placement, is 30 minutes a length of；It takes out titanium metal containment and is consolidated mounting base in workpiece blue box, workpiece blue box
Locating environment is vacuum environment, and vacuum environment pressure is -0.05Mpa；Environment vacuum locating for workpiece blue box is evacuated to 3.0E-
2Pa vacuum degree, is then sintered, and sintering temperature gradually rises to 650 degrees Celsius, a length of when sintering temperature gradually rises
1.5 hours；Environment vacuum locating for workpiece blue box is evacuated to 10pa hereinafter, keeping the temperature 45 under being 650 degrees Celsius in sintering temperature
Minute, sintering temperature is risen to 1050 degrees Celsius later, 2 hours is kept the temperature, terminates to be sintered later；By ring locating for workpiece blue box
Border temperature is down to 100 degrees Celsius hereinafter, taking out titanium metal containment.
Industrially pure titanium because there are also carbon, nitrogen, hydrogen, oxygen, etc. impurity, transformation temperature is at 900 degree or so；Titanium alloy again because
It is different to add alloying element, rough segmentation is three types: α alloy, two phase alloys (alpha+beta alloy), beta alloy；
It is subdivided into five kinds: α alloy, nearly α alloy, two phase alloys (alpha+beta alloy), nearly beta alloy, beta alloy；Titanium alloy according to point
Class is different, and tissue and technique, performance are variant.In general, α alloy, nearly α alloy microscopic structure to be substantially α isometric
Tissue, has a small amount of β phase, because of β phase；The microscopic structure of two phase alloys (alpha+beta alloy) is isometric nascent alpha+beta transformation tissue, because
It is high-temperature-phase for β phase, is at high temperature exactly β phase, but in cooling procedure because unstable, strip α phase, strip at this moment is precipitated
α phase is in order to other with previous isometric alpha phase zone, so referred to as secondaryαphase, but β phase will not be completely reformed into secondaryαphase, institute again
Can also remain, referred to as remnants β phase.So the high temperature microstructure of diphasic titanium alloy is alpha+beta, room temperature texture is isometric first
Raw alpha+beta transformation tissue (i.e. isometric primary α+strip secondaryαphase+remnants β)；It is all β phase, α phase that nearly beta alloy alloy, which is exactly most of,
It is less, it is dissolved generally more than transformation temperature, entirely β phase.
After adopting the above technical scheme, use value is high the invention has the following beneficial effects: preparation process is simple, can increase
Aesthetics, brightness, the durability on titanium metal containment surface, robustness is stronger, superior performance and generalization in colleague field
By force.
The above is only used to illustrate the technical scheme of the present invention and not to limit it, and those of ordinary skill in the art are to this hair
The other modifications or equivalent replacement that bright technical solution is made, as long as it does not depart from the spirit and scope of the technical scheme of the present invention,
It is intended to be within the scope of the claims of the invention.
