Abstract:
Provided are stainless steel-resin composite and method of preparing the same. The method comprises steps of: providing a stainless steel substrate; spraying aluminum particles onto a first surface of the stainless steel substrate via thermal spraying to form an aluminum layer on the first surface of the stainless steel substrate; removing the aluminum layer via dipping the stainless steel substrate into an alkaline solution with a p H value greater than or equal to 10 so as to form a porous surface; and injecting a resin composition onto the porous surface of the stainless steel substrate so as to form a resin layer.
