## 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.

## Claims

### Claim 1

a stainless steel part having nano-pores defined in a surface thereof; and
an amorphous alloy part integrally bonded to the surface having the nano-pores.

### Claim 2 (depends on 1)

The composite as claimed in claim 1, wherein the nano-pores have an average diameter of about 30 nm-60 nm.

### Claim 3 (depends on 1)

The composite as claimed in claim 1, wherein the amorphous alloy part is made of an amorphous alloy selected from the group consisting of magnesium-based amorphous alloy, zirconium-based amorphous alloy, and copper-based amorphous alloy.

### Claim 4 (depends on 3)

The composite as claimed in claim 3, wherein the amorphous alloy having a super-cooled liquid region larger than 20° C.

### Claim 5 (depends on 3)

The composite as claimed in claim 3, wherein the onset temperature of crystallization of the amorphous alloy is lower than 500° C.

### Claim 6 (depends on 1)

The composite as claimed in claim 1, wherein portions of the amorphous alloy part penetrating in the nano-pores.
