Description

technical field [0001] The present invention relates to heat-resistant and corrosion-resistant protection on the surface of iron cookware, in particular to an improved heat-resistant and corrosion-resistant thermal spray coating, which has excellent heat and corrosion resistance. Correspondingly, the present invention also provides the Method of preparation of coatings. Background technique [0002] Electromagnetic induction products in the cookware industry often use iron thermal spray layer as a magnetic and thermal conductive material layer. However, due to the active chemical properties of elemental iron, it is easy to rust when exposed to air, and pure iron itself has poor flexibility and is easy to rust. Scratch induction hobs. In order to overcome this defect, those skilled in the art usually need to continue thermally spraying a certain thickness of aluminum layer on the iron thermal spray layer, in order to achieve the effect of antirust and reducing scratches on t...
