Title:
HARD COATING AND MEMBER COATED WITH HARD COATING
Document Type and Number:
WIPO Patent Application WO/2020/026390
Kind Code:
A1
Abstract:
In the present invention, two types of nanolayer alternating layers 38, 40, in which an A-layer 32 as a single-composition layer of one of an A-composition (AlCr α nitride), a B-composition (AlTiCr β nitride), and a C-composition (AlCr(SiC) γ nitride), and two of an A-composition, a B-composition, and a C-composition nanolayer layer (nanolayer A layer 32n, nanolayer B-layer 34n, nanolayer C-layer 36n) are alternately layered, are alternately layered with a predetermined film thickness, whereby excellent wear resistance, toughness, lubricity, and welding resistance are obtained. An increase in service life of a tool can thereby be realized in cutting of, e.g., alloy tool steel, stainless steel, carbon steel, cast iron, alloy steel, and various other materials to be cut, or in high-speed machining, dry machining, and other harsh machining conditions.
