Title:
ELECTRIC DISCHARGE SURFACE TREATING ELECTRODE AND PRODUCTION METHOD THEREOF AND ELECTRIC DISCHARGE SURFACE TREATING METHOD
Document Type and Number:
WIPO Patent Application WO/2001/023641
Kind Code:
A1
Abstract:
An electric discharge surface treating electrode (10) is formed by mixing cBN powder (11) with Co powder (12), the both being insulating hard substances, and the mixture is charged in a press die for compression molding, and electric discharge is generated between the electrode (10) and a work (16) by an electric discharge surface treating power supply device (17) to form a hard coat (20) which consists of a cBN-and-Co alloy and has a high hardness under a high-temperature environment on the work (16).
