Abstract

An electronic atomization device (300), an atomizer (100), an atomization core (10), and a preparation method therefor are provided. The atomization core (10) includes a porous substrate (11), a heating layer (12), and a protective layer (13); the porous substrate (11) has an atomization surface (111), the heating layer (12) is disposed on the atomization surface (111) of the porous substrate (11), the protective layer (13) is disposed on the surface of the heating layer (12) away from the porous substrate (11), the protective layer (13) includes metallic aluminum and alumina, and the alumina at least partially covers the surface of the metallic aluminum to form an alumina layer (132). Therefore, it may reduce failure of the heating layer on the atomization core (10) due to oxidization when in direct contact with air in the atomization process, which affects stability and the service life of the atomization core (10).
