Title:
WEAR-RESISTANT SURFACE-COATED MATERIAL
Document Type and Number:
Japanese Patent JPH0649687
Kind Code:
A
Abstract:
PURPOSE: To improve the wear resistance and cutting life by coating the surface of a conductive or nonconductive hard base material having a specified hardness with the film of a metal boride having a higher hardness.
CONSTITUTION: This wear-resistant surface-coated material is formed by coating the surface of a conductive or nonconductive base material (WC-Co, cermet) or a nonconductive hard base material (alumina, zirconia, etc.). The hard base material has ≥1000 hardness (Hv). The metal boride film has ≥2000 hardness (Hv) and is formed by nonaqueous electrolysis or through a conductive substrate (Ni, Co, etc.) layer. The metal boride coating film can be further coated with a Ti compd. (TiN, TiC) film.
