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
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A stainless steel-and-amorphous alloy composite, comprising:
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.
2 . The composite as claimed in claim 1 , wherein the nano-pores have an average diameter of about 30 nm-60 nm.
3 . 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.
4 . The composite as claimed in claim 3 , wherein the amorphous alloy having a super-cooled liquid region larger than 20° C.
5 . The composite as claimed in claim 3 , wherein the onset temperature of crystallization of the amorphous alloy is lower than 500° C.
6 . The composite as claimed in claim 1 , wherein portions of the amorphous alloy part penetrating in the nano-pores.Join the waitlist — get patent alerts
