Abstract

The invention relates to a densely structured magnetically permeable coating and a preparation method thereof. A magnetically permeable coating with a dense structure is applied as a layered coating on the surface of a base material. The magnetically permeable coating is made by a cold spraying process, and the porosity of the magnetically permeable coating is 0.05-0.25%. The magnetically conductive coating of the present invention has the characteristics of high density, strong binding force, and is not easy to fall off, and has a porosity of 0.05 to 0.25%, which has the beneficial effect of improving the binding force of the magnetically conductive coating and electromagnetic heating power, which is lower than this range , it will lead to the problem of difficulty in the implementation of the process; if it is higher than this range, it will lead to the problem of the decrease of the bonding force of the magnetic permeable coating and the electromagnetic heating power. The invention also relates to a preparation method of a magnetically conductive coating with a dense structure, as well as a pot body and a cooking utensil with the magnetically conductive coating.

Description

technical field

[0001] The invention relates to the technical field of cooking utensils, in particular to a magnetic conductive coating with a dense structure and a preparation method thereof. Background technique

[0002] Aluminum alloy, 304 stainless steel and other materials are widely used in household appliances, but the electromagnetic heating function of these non-magnetic or weakly magnetically conductive pots is not ideal. For example, aluminum IH heating pressure cooker or frying pan, etc., the traditional process part adopts hot pressing brazing or riveting to prepare a layer of magnetically conductive 430 stainless steel sheet at the bottom of the base pot. However, these two processes cannot solve the problem of the high-position double bottom stainless steel plate of the pot body, and the electromagnetic heating power is small. Especially in the latter riveting process, when the iron plate (or 430 stainless steel) composite process is performed on the bottom o...
