The application provides a heater, a preparation method of the heater and a smoking set. The heater is used for heating an aerosol forming substrate, volatilizing at least one component in the aerosol forming substrate and forming an aerosol for a user to smoke. The heater comprises a substrate and a heating film. The heating film is covered on the surface of the substrate. The material of the heating film is one or more of iron, iron alloy, nickel, nickel alloy, chromium, chromium alloy, titanium, titanium alloy, aluminum and aluminum alloy. The thickness of the heating film is 0.01-5 microns. The heating film can heat the aerosol forming substrate through the combination of infrared radiation and contact heat conduction, so that the heating film is electrified and generates heat to promote the decomposition of the aerosol forming substrate. The heating film is prepared based on the overall inventive concept of preparing a thin film structure of a base metal or a base metal alloy. The heating film can completely cover the substrate, the heating is uniform, the infrared radiation emissivity can be reduced, and the heat loss can be reduced.

The present invention provides a preparation method of an interface layer for connecting dissimilar metals and a welding method based on the interface layer. The first step is to deposit a layer of AlNi intermetallic compound film with a thickness of nanometers on the surface of steel by a vapor deposition method, and the AlNi intermetallic compound has a simple cubic structure; the second step is to use the nanometer-scale AlNi intermetallic compound film deposited on the surface of the steel as the interface layer for connecting the magnesium alloy and the steel; the third step is to use an ultrasonic spot welding method to achieve the metallurgical connection of the magnesium alloy / steel with a pre-set AlNi intermetallic compound layer, and to obtain the interface connection structure of the magnesium alloy / AlNi intermetallic compound layer / steel by optimizing the welding process parameters. The present invention controls the type and thickness of the interface layer by pre-setting the interface layer, and at the same time promotes the metallurgical reaction between the interface layer and the alloy elements of the parent materials on both sides, and maintains the structural integrity of the interface layer. The method has the characteristics of adjustable type and thickness of the interface layer, is convenient for mass production, and can expand the scope of application.
