Abstract

The invention relates to an electromagnetic coating for the bottom of a liner of a cooker such as an electric cooker and a manufacturing method of the electromagnetic coating. The highest power utilization ratio of the electromagnetic coating can reach 97%. The coating is prepared from mixed powder composed of nickel and 430 stainless steel by using a high-pressure cold spraying process, so that the electromagnetic coating is formed at the bottom of the cooker prepared from a matrix such as an aluminum matrix and stainless steel. By using the coating, the bottom of the liner of the cooker such as the electric cooker prepared from a metal matrix, a ceramic matrix or a glass matrix without magnetic conductivity or with poor magnetic conductivity not only has excellent magnetic conductivity and very high electromagnetic heating efficiency, but also has ideal corrosion resistance, and the overall performance of an electromagnetic cooker is improved.

Description

technical field [0001] The invention belongs to the field of metal material research and provides a method for preparing a high-performance electromagnetic coating on the bottom of inner tanks of electric rice cookers and other pots by means of a cold spraying process. Background technique [0002] Due to the small specific gravity, non-toxicity, strong corrosion resistance and easy processing of aluminum materials, the inner tank of today's rice cookers is mostly made of aluminum, but aluminum is a non-magnetic material. If you want to heat the pot body by electromagnetic, it is usually in the pot. The bottom of the gallbladder is inlaid with an iron plate to achieve magnetic conduction. This method is not only cumbersome to process, but also increases the weight. The bigger problem is that the iron plate has poor magnetic conductivity, and the power utilization rate can only reach 55-58%, which is far from meeting the requirements. [0003] With the development of thermal...
