Abstract

The invention relates to a protection method for the anodic oxidation of an aluminum-stainless steel compounded cooker, belonging to the technical field of cooker processing. For solving the problem that currently, an ink coating is adopted for protection, due to the existence of a punch-through phenomenon, pitting corrosions are produced on stainless steel and are difficult to remove, the invention provides a protection method for the anodic oxidation of an aluminum-stainless steel compounded cooker, and the method comprises the following steps of carrying out machine shaping on an aluminum-stainless steel compounded material so as to manufacture a corresponding aluminum-stainless steel compounded cooker workpiece; then, covering a prefabricated hard plastic film on the position of a stainless steel sheet of the cooker workpiece, so that an effect of sealing is achieved; carrying out anodic oxidation on the obtained object, so that an anodic oxidation film is formed on the surface of an aluminum alloy; and removing the hard plastic film covered on the position of stainless steel, and post-processing the obtained product, so that an aluminum-stainless steel compounded cooker is obtained. The method disclosed by the invention has the advantages that the method is simple in operation, and stainless steel is not corroded in the process of anodic oxidation.

Description

technical field [0001] The invention relates to an anodic oxidation protection method for aluminum-stainless steel composite cookware, which belongs to the technical field of cookware processing. Background technique [0002] In the cookware industry, aluminum alloy is widely used for its good thermal conductivity and energy saving, but its disadvantage is poor wear resistance, which limits its application in some occasions. However, stainless steel is highly praised for its hardness, wear resistance, and non-reaction with food. In addition, ferritic stainless steel has magnetic conductivity, which can be used as a contact material for induction cookers, and is also widely used in the cookware industry. However, due to the poor thermal conductivity of stainless steel materials, it often causes local overheating and affects cooking. The aluminum-stainless steel composite material, which combines the advantages of the two materials and avoids the disadvantages of the two mate...
