This invention relates to the field of metal surface treatment technology. The method first involves anodizing an aluminum alloy sheet in a sulfuric acid electrolyte to obtain a porous oxide film. Then, using this film as the cathode, ultrasonic pulse electrochemical sealing is performed in a colloidal sealing solution containing an oxidant, organic fuel, and a boron source. Utilizing the ultrasonic cavitation effect and the relaxation characteristics of the pulsed electric field, directional deposition of colloidal particles deep within the micropores is achieved. Finally, gradient heat treatment completes low-temperature drying, liquid-phase pre-melting, self-propagating reaction initiation, and densification sintering. This method optimizes mass transfer and buffers thermal stress through a boron-source molten liquid-phase medium. It utilizes an in-situ self-propagating exothermic reaction to create localized high temperatures, promoting the transformation of the pore filler into a chemically inert, dense ceramic phase. This solves the problems of high-temperature cracking in traditional hydrated sealing layers and air pockets at the bottom of conventional physical filling pores, improving the high-temperature resistance, thermal shock resistance, and long-term chemical corrosion resistance of high-strength aluminum alloy sheets such as 6061 and 7075.

The utility model discloses a kind of heating stove for barbecue and hot pot, to solve the single function of existing barbecue stove, hot pot equipment and heating stove, cannot simultaneously satisfy the problem of multifunctional demand. The heating stove includes furnace body, and the upper end of furnace body is equipped with baking tray, and first heat source is equipped below baking tray. Second heat source is further equipped in furnace body, and the side wall of furnace body is equipped with the air-permeable net that second heat source and outside are conducted, realize heating function. First heat source and second heat source can use organic fuel, can also use electric power heat energy, and first heat source and second heat source can be used alone. To further improve heating effect, reflector and fan are parallelly equipped in furnace body, and second heat source is located between the two, wherein reflector is usually bowl-shaped structure towards second heat source. The utility model effectively integrates barbecue, hot pot and heating function, and gives consideration to aesthetics and convenience, greatly improve the practical value and user experience of product.
