Title:
超硬合金製鋏及びその製造方法
Document Type and Number:
Japanese Patent JP6743334
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide scissors made of cemented carbide, each tip of which made of cemented carbide and having an excellent mechanical properties is firmly joined to a metal substrate, the scissors made of cemented carbide also capable of exhibiting both of abrasion resistance property of the cemented carbide and flexibility of the metal substrate and a low cost and simple manufacturing method thereof.SOLUTION: A manufacturing method of scissors made of cemented carbide comprises: a first step for forming a recessed part in one of metal plates; a second step for forming a thermal sprayed cemented carbide coating film in the recessed part up to a height substantially the same as that of a surface of the metal plate; a third step for forming a modified part by applying a friction agitation process to at least a part of the thermal sprayed cemented carbide coating film; and a fourth step for processing the metal plate to a scissors shape so that the modified part becomes at least a part of the tip of the scissors.SELECTED DRAWING: Figure 1
