Copper / graphene junction, its manufacturing method, and copper / graphene junction structure

摘要

Problem: the copper member made of copper or copper alloy and the graphene containing carbon containing the graphene aggregate are strongly bonded to each other, and no peeling occurs even during the cold cycle loading. Problem to be solved: to provide a copper / graphene junction excellent in cold cycle reliability and a manufacturing method thereof.Copper / graphene junctionCopper and copper alloy membersGraphene containing carbonaceous component containing graphene aggregateIs a copper / graphene junction having a bonded structure;Between the copper member and the graphene containing carbon memberOn the carbonaceous member containing grapheneTi,Zr,NBAn active metal carbide layer containing carbide of one or more active metals selected from HF is formedBetween the active metal carbide layer and the copper memberMg solid solution in which mg is dissolved in the mother phase of Cu is formed.Diagram
