Has the inner surface of matrix, to obtain the titanium alloy coating with excellent decay resistance, then without the interior table in pan matrix
Spraying fluororesin etc. corrosion resistant organic coating in face can reach effectively protection pot so that pan has excellent decay resistance
The long-term non-corrosive of inner surface of tool, the purpose not failed, and cold spray process production efficiency is high, and processing cost is low, while nothing
The mechanics or thermal characteristic of pan matrix need to be taken into account, the manufacturing cost of product can be effectively reduced.
Further, the titanium alloy powder includes titanium-aluminum-vanadium alloys powder；The particle diameter of the titanium alloy powder is：10
μm~50 μm；And the default cold spraying parameter includes：Powder feed rate is：5kg/h~15kg/h, cold spraying work gas
The injection pressure of body is 1MPa~3Mpa, injection temperation is 0K~873K, jet velocity 1m3/ min~2m3/ min, jet length
From for 10mm~50mm, cold spraying consumption power is 5KW~25KW.
In this embodiment, the sandblasting using cold spray process by titanium alloy powder cold spraying to the inner surface of pan matrix
During the titanium alloy coating that pan is formed on coating, Titanium Powder is transmitted with 5kg/h~15kg/h powder delivery speed
End, so that it is guaranteed that ample supply of the titanium alloy powder in spraying process, and then be 1MPa~3Mpa, spray temperature in injection pressure
Spend for 0K~873K, jet velocity 1m3/ min~2m3It is in the presence of/min cold spraying working gas that titanium alloy powder is defeated
Enter high velocity air in the form of complete solid-state, the inner surface of 10mm~50mm jet length shock pan matrix, so as to polymerize
One layer of fine and close titanium alloy coating is formed, further in order to ensure spraying effect, the cold spraying in whole cold spray process disappears
Wasted work rate can be preferably held in 5KW~25KW；Certainly, it will be apparent to a skilled person that the tool of above-mentioned parameter
Body arranges value can be according to the different and otherwise varied of pan matrix, and other can lift cold spraying titanium alloy powder and form pot
The parameter value of the spraying effect of the titanium alloy coating of tool is also in the scope of protection of the utility model.
In the above-described embodiments, cold spraying working gas generally comprises air, helium, nitrogen or mixed gas.
Further, the thickness of the titanium alloy coating is：30 μm~1000 μm；The porosity of the titanium alloy coating is small
In 1.5%.
In this embodiment, the titanium alloy coating that the inner surface of pan matrix is formed is one layer of thin and dense coating, tool
Body, the span of its thickness is preferably 30 μm~1000 μm, and because porosity is lower, coating is finer and close, coating
Quality is higher, therefore the porosity of titanium alloy coating can be set to be less than 1.5%, is applied with ensuring to obtain the titanium alloy of even compact
Layer, so that the inner surface of pan can reach long-term corrosion resistant effect；And the setting of the specific thickness value of titanium alloy coating can
With according to actual use demand setting.
Step S38, grinding and buffing processing is carried out to the titanium alloy coating.
In this embodiment, can be to spraying shape in order to further ensure that the finish of the inner surface of pan and aesthetic property
Into titanium alloy coating carry out grinding and buffing processing, further by grinding and buffing handle titanium alloy coating it is coarse
Degree should be at least below 10 μm, so that its surface has higher finish, the smaller finish of roughness is higher, for example can be less than
2μm。
To sum up, aluminum or the interior table antirust coat of iron material pan are used as using titanium alloy coating, it is ensured that pan is being cooked a meal
During boiling, inner surface has good decay resistance.Titanium alloy coating have certain thickness (30 μm~1000 μm) and
Very high compactness (porosity<1.5%), and it possesses the function of the corrosion such as excellent acid and alkali resistance salt, can effectively prevent to corrode
The intrusion of medium, ensure that whole pan inner surface need not spray the organic rust preventing coating such as fluororesin, that is, can guarantee that pan inner surface
Possesses good anticorrosion effect for a long time, the features such as failure for a long time.
The technical solution of the utility model is described in detail above in association with accompanying drawing, by using cold spray process in pan
Inner surface sprays one layer of titanium alloy coating that is thin and compact, having excellent decay resistance so that pan have it is excellent
Decay resistance, the long-term non-corrosive of inner surface of pan is kept not fail, so as to extend the service life of product.
