A kind of antirust pot
Technical field
The utility model belongs to articles for daily use technical field, more particularly to a kind of antirust pot.
Background technology
Titanium alloy pot is that the alloy pot to be formed is made as matrix material using titanium alloy.The kind for the pot sold in the market
Class is more, is all iron pan, aluminum pot, stainless-steel pan three major types from most of material pot.The iron pan biography the most frequently used as the common people
System cooker, people's mistake thinks a small amount of ferro element that iron pan cooking is dissolved out, is easily absorbed by the body, and can effectively prevent from lacking
Iron anaemia occurs, and has very much benifit to the health of human body.It is studies have shown that former by the oxygen in the iron atom and air in iron pan
The iron rust that son occurs electrochemical reaction and generated easily produces disease of the liver, and causes the infringement to human liver.Aluminium because heat transfer is good and
Pot material use is widely used as, fuel can be both saved using aluminum pot, the time required to and can saves culinary art.But research is found,
Long-term use of aluminum products, which make cooker, can make aluminium excess intake, unfavorable to health.The property of aluminium is active, easily occurs with other materials
Chemical reaction, very easily chemically reacted with acid, alkali, salt.During cooking, a part of aluminium on aluminum pot will because acid,
The effect of alkali, salt is infiltrated in dish is eaten by people, will produce harm to human body over time.Excessively taking the photograph people's aluminium for a long time can cause morning
Decline, or even senile dementia can be caused.
Titanium is a kind of important structural metal to grow up the 1950s, and titanium alloy is because high, anti-corrosion with intensity
The features such as property is good, heat resistance is high.Titanium alloy is reported for manufacturing pot, such as Chinese invention patent
CN201310291914.3 titaniums or titanium alloy composite pot and preparation technology disclose is used for pot using high-new vacuum coating technology
Surface treatment, it is that vacuum titanizing or titanium alloy processing are carried out on traditional pot surface, and such as in pot surface vacuum titanium-nitride, its is true
Empty film thickness reaches 1 to 5 microns.Make a pot surface passivation, prevent the metallic element that pot is harmful in using process type from dissolving in food
In the mankind are damaged.A kind of preparation methods of titanium copper compound pot of Chinese invention patent CN201210205112.1 disclose
Pot is made with Titanium board punching press, then copper electroplating layer, the pot after copper electroplating layer is placed in immersion treatment in post-treatment solution
Obtain titanium copper compound pot.Chinese utility model patent CN201320715463.7 discloses a kind of titanium pot, including using pure titanium or
Pot, the bottom of a pan and handle made of titanium alloy, pot and the bottom of a pan are fixedly connected by welding, and handle is by being welded to connect in pot
On.The utility model titanium pot is made of the method for welding, and its preparation method is simple and easy to operate, is saved material, is avoided tradition
The drawbacks of pot method processed.And the pot done using titanium, the effect such as there is corrosion-resistant, easy cleaning, will not get rusty, be antibacterial.
The problem of anti-wear performance deficiency be present in most of pot being fabricated to using pure titanium or titanium alloy, if pot is done
It is too thick, then in the presence of a heat conduction and cost the problem of.If pot matrix material is done it is thin, cover other metal levels formed it is multiple
Layer is closed, then the problem of complex operation and covering layer adhesion be present.Therefore, how to obtain one it is simple to operate, and can be simultaneously
Improve pot wearability, the production technology of corrosion resistance, be improve titanium or titanium alloy pot can practicality key.
Utility model content
In order to solve the problems, such as that prior art is present, the purpose of this utility model be to provide a kind of manufacture craft it is simple,
The titanium alloy substrate pot of wearability and fine corrosion resistance.
To achieve the above object, the technical solution adopted in the utility model is:A kind of antirust pot, including pot body and the bottom of a pan,
The pot body is common aluminum alloy material, and the matrix material in the bottom of a pan is titanium alloy, and titanium alloy substrate side is oozed for plasma
Carbon-coating, one layer of high-temperature resistant coating coating, opposite side coating high-temperature resistant coating coating are covered on plasma carburising layer.
Further, before the plasma carburising, one layer of microcosmic etch layer, Ran Hou are formed on titanium alloy substrate surface
Carburized layer is formed in etch layer.
Further, the pot body and the bottom of a pan are manufactured respectively, then by being welded together.
Further, the bottom of a pan edge and pot body joint portion are pure titanium alloy substrate material, do not do carburizing or coating
Processing.
Further, the trade mark of the titanium alloy is TA2, TC4 or TC6.
Further, the thickness of the plasma carburising layer is 20~40 μm.
Further, the high-temperature resistant coating coating is organosilicon fire-resistant nano paint, and its coating layer thickness is 10~15
μm。
The beneficial effects of the utility model are:
1st, the bottom of a pan of pot described in the utility model uses titanium alloy material as matrix, ensure that the certain corrosion resistance in the bottom of a pan
Energy.In addition, employing glow plasma non-hydrogen carbonizing technique obtains carburized layer so that the bottom of a pan surface Vickers hardness reaches
650~800HV1, drastically increase the bottom of a pan surface abrasion resistance.Meanwhile the carburizing obtained under hydrogen-free plasma carburising technique
Layer decay resistance than matrix will not severe exacerbation, ensure that the corrosion-resistant person's character of certain titanium alloy.
2nd, because the surface that shock is often rubbed against with desktop, support, body of heater etc. is the bottom of a pan, and the friction to pot body is less,
Therefore pot body and the bottom of a pan split-type design are used so that pot body is the thin-walled of common aluminum alloy material manufacture, and the bottom of a pan uses carburizing
Wearability is improved, meets very much routine use custom, also saves material, reduce cost.
3rd, due to having the phenomenon of deterioration to the welding performance of material after carburizing, therefore the bottom of a pan edge is pure with pot body joint portion
Titanium alloy substrate material, does not do Carburization Treatment, is advantageous to pot body and the bottom of a pan is smoothly weldingly connected.
4th, organosilicon heat-resistant nano-paint is coated on the inside of carburized layer or pot, is advantageous to further improve the resistance to of pot
Corrosive nature.
