Problems solved by technology
However, due to the limitations of its own technology, explosive welding has the disadvantage of generating noise and seismic waves in the production process, which will affect the environment and residents near the explosion site, so explosive processing plants are generally built in remote mountainous areas
At the same time, the open-air operation of explosive processing is greatly affected by the weather

Embodiment Construction
[0024] according to Figure 1-5 The present invention will be described in detail. The invention adopts advanced composite plate technology in the aerospace field to diffusely weld two metals with a melting point difference of 1000°C between titanium and aluminum into composite plates, which are then further processed into pots.
[0025] The present invention mainly includes two parts. The first part is the manufacturing method of titanium-aluminum composite material (titanium-aluminum composite plate): first, the bonding surface of the titanium thin plate 10 and the aluminum plate 11 is mechanically polished and cleaned. In the vacuum vessel 6, the vacuum degree is 10 -2 - 10 -5 Pa, temperature 520°C~600°C, pressure 6~10N / mm 2 The vacuum diffusion welding takes 0.5 to 1 hour under the best process conditions. Among them, the temperature of the vacuum vessel 6 is in the best range of 550 to 600°C. Then it is naturally cooled to room temperature, the vacuum container 6 is opened, ...

Abstract
The invention relates to a Ti-Al complex metal cooking pot manufacture method, which is a special process for manufacturing modern high-end cooker materials and high-end cookers. The manufacture method comprises the following steps: polishing the joint surfaces of a thin Ti sheet and a round Al sheet to be complexed; placing the thin Ti sheet and the round Al sheet into a vacuum container; carrying out vacuum diffusion welding for 0.5 to 1 hour under the conditions that the vacuum degree is 10<-2> to 10<-5> Pa, the temperature is kept at 520 to 600 DEG C and the pressure is 6 to 12 N / mm<2>; naturally cooling to room temperature; taking Ti-Al complex plate from the vacuum container; stretching the Ti-Al complex plate by a stretching die to form a pot body structure; cutting and trimming the pot blank; polishing the inner surface and the outer surface of the pot blank; anodizing the outer surface; drilling holes on the pot body; and mounting a proper handle or handles to obtain the cooking pot product. The cooker manufactured by the method can be used on any kind of stoves, and has predominant advantages compared with the conventional pot.
Description
Technical field [0001] The invention relates to the technical field of cooking utensils, including composite metal material production, composite metal material cold processing molding, surface electrochemical treatment and other disciplines industries, and specifically relates to a method for manufacturing a titanium aluminum composite metal cooking pot. Background technique [0002] Titanium is a modern high-tech material, widely used in aerospace, fine chemicals, medical and other industries. As far as life sciences are concerned, titanium is a biophilic metal, and it has no toxic and side effects when transplanted into the human body for decades. It has been confirmed that titanium can stimulate phagocytes and enhance immunity; titanium is still The only metal that has no effect on autonomic nerves and taste nerves. Therefore, titanium metal is a very ideal material for making pots. However, the thermal conductivity of elemental metal titanium is relatively poor, only 1 / 16 ...
