Abstract
A stainless steel-and-resin composite includes a stainless steel part and a resin part bonded to the stainless steel part. The stainless steel part has a porous film resulted from anodizing formed thereon. The porous film defines pores with an average diameter of about 100 nm-500 nm. The resin part is integrally bonded to the surface of the stainless steel part having the porous film, with portions of the resin part penetrating in the pores. The resin part mainly comprises crystalline thermoplastic synthetic resin.
Claims18
A stainless steel-and-resin composite, comprising:
- a stainless steel part having a porous film formed on a surface thereof, the porous film having pores with an average diameter of about 100 nm-500 nm;
- and
- a resin part integrally bonded to the surface of the stainless steel part having the porous film, with portions of the resin part penetrating in the pores, the resin part mainly comprising crystalline thermoplastic synthetic resin.
A method for making a stainless steel-and-resin composite, comprising:
- providing a stainless steel part;
- activating the stainless steel part to remove natural oxide of iron formed thereon;
- anodizing the stainless steel part to form a porous film, the porous film defining pores having an average diameter of about 100 nm-500 nm;
- positioning the stainless steel part in a mold;
- and
- injecting crystalline thermoplastic synthetic resin on the porous film to form a resin part integrally bonded to the stainless steel part when hardened, the crystalline thermoplastic synthetic resin filling the pores of the porous film.
