Abstract
A stainless steel-and-amorphous alloy composite includes a stainless steel part and an amorphous alloy part. The stainless steel part has nano-pores defined in a surface thereof. The amorphous alloy part is integrally bonded to the surface having the nano-pores. A method for manufacturing the composite is also described.
Claims13
A method for making a stainless steel-and-amorphous alloy composite, comprising:
- providing an stainless steel part;
- electrochemically etching the stainless steel part to form nano-pores on a surface thereof;
- pre-heating the stainless steel part;
- positioning the stainless steel part in a mold;
- and
- molding molten amorphous alloy on the surface having the nano-pores to form an amorphous alloy part integrally bonded to the stainless steel part when hardened, the molten amorphous alloy being at a temperature of about (Tg+5) ° C. to about (Tx-10) ° C., wherein the Tg and Tx are the onset temperature of glass transition and the onset temperature of crystallization of the amorphous alloy respectively.
