Abstract

PURPOSE: To enhance the bond strength at the interface of a cutting edge layer of a diamond-base sintered material and a holding layer of a TiC-contg. W-base alloy and improve machning life by forming a composite sintered piece for cutting edge into the laminated composite body of said cutting edge layer and holding layer.
CONSTITUTION: A composite sintered piece for cutting edge is constituted of a laminated composite body of a cutting edge layer comprising a diamond-base material and a holding layer comprising a W-base alloy contg. 10W50pts.wt. TiC and W and unavoidable impurities for the remainder and, if necessary, added with 0.1W 20% one or more kinds of carbide of Zr, Hf, V, Nb, Ta, Ca, Mo and W. This yields the hilding layer having superior toughness and heat and abrasion resistances, enhances the bond strength of the cutting edge layer and the holding layer and makes this piece suitable for machining of hard-to-machine materials.
