Protective gas；
Step 4: sintering temperature is reduced to 200 degrees Celsius, is sintered 2-3 hours, is taken out after sintering, and with distilled water into
Row cooling, until reaching room temperature；
Step 5: the titanium cookware for having dropped temperature is soaked with magnalium strontium yittrium alloy etchant, a length of 35-55 points when soaking
Clock soaks and takes out natural air drying later, take pictures using metallographic microscope can be obtained metallographic structure.
Grind specific steps in the step 1 are as follows: by hand successively using granularity be 400#, 600#, 1000#, 1600#,
The sand paper of 2000# is ground specimen surface.
In the step 2, primary sintering temperature is 700 degrees Celsius, 30 minutes a length of when being tentatively sintered.
Magnalium strontium yittrium alloy etchant concentration is 10mol/l in the step 5.
Sintering temperature is promoted to 1100 degrees Celsius in the step 3, is sintered 1.5 hours.
A length of 45 minutes when being soaked in the step 5.
The working principle of the invention: titanium cookware surface is ground, and is carried out on metallic phase polisher milling after the completion of grinding
Mechanical polishing is dried up after the titanium cookware washes of absolute alcohol for completing polishing is clean with hair dryer；By the titanium after drying
Metal pan is placed in workpiece blue box, and keeping the environment of workpiece blue box is vacuum state, is carried out to titanium cookware preliminary
Sintering, primary sintering temperature is 600-800 degrees Celsius, 20-35 minutes a length of when being tentatively sintered；Sintering temperature is promoted to 1000
It ± 100 degrees Celsius, is sintered 1-2 hours, was during which filled with protective gas every 20 minutes；Sintering temperature is reduced to 200 degrees Celsius,
Sintering 2-3 hours, takes out, and cooled down with distilled water after sintering, until reaching room temperature；The titanium cookware for having dropped temperature is used
Magnalium strontium yittrium alloy etchant soaks, 35-55 minutes a length of when soaking, and soaks and takes out natural air drying later, uses metallography microscope
Mirror take pictures can be obtained metallographic structure.
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.
