AMORPHOUS CARBON COVERING TOOL AND COVERING METHOD FOR AMORPHOUS CARBON COATING

摘要

PROBLEM TO BE SOLVED: To provide an amorphous carbon covering tool which has a low coefficient of friction, high hardness and suitable toughness and an effect of restraining crack development while maintaining effective adhesion reduction and to provide a covering method for amorphous carbon coatings.;SOLUTION: This tool is an amorphous carbon covering tool covered with the amorphous carbon coating. The amorphous carbon coating has 0.30 or more and less than 0.42 in π bonding/σ bonding which is a strength ratio of π bonding to σ bonding.;COPYRIGHT: (C)2006,JPO&NCIPI
