Title:

ホットスタンプ用被覆金型

Document Type and Number:

Japanese Patent JP7318662

Kind Code:

B2

Abstract:

A coated die for use in hot stamping has a hard film having an alternating lamination section formed by alternating lamination of a1 layers consisting of nitride having 30% or more of chromium in atomic ratio in a metal part, and a2 layers consisting of nitride having 50% or more of vanadium in atomic ratio in a metal part. When ta1 and ta2 are defined as thicknesses of the a1 layer and the a2 layer respectively, a film thickness ratio Xb is defined as a film thickness ratio ta2/ta1 of a1 layers and a2 layers adjacent to each other in a substrate-side region of the alternating lamination section and a film thickness ratio Xt is defined as a film thickness ratio ta2/ta1 of a1 layers and a2 layers adjacent to each other in an outermost surface side region of the alternating lamination section, it holds that Xt>Xb.
