Investigation on Brazing of Carbon Film Deposited Diamond for Cutting Vehicle Tyre

关键字:Brazed Diamond; Carbon film; Interfacial microstructure; Vehicle tyre

摘要:The super brazed diamond saw was developed to cut efficiently vehicle tyre in the research. The carbon film deposited diamond and the uncoated diamond were brazed with NiCr alloy by high-frequency induction heating under argon atmosphere at 1030 degrees C for 30 seconds respectively. The interfacial microstructures between the brazed diamond and the filler alloy were analyzed by the advanced testing technologies. The results shows that long-lath carbides with the definite orientation and better flatness are closely arrayed on the brazed uncoated diamond surface and Cr-carbides forms normally and compactly on the surface of carbon film deposited diamond brazed. That is because the carbon film has changed the mechanism of Cr-carbides forming on the surface of diamond brazed. The test of cutting vehicle tyre shows that the use life of the brazed deposited diamond saw is much longer than that of the brazed uncoated diamond saw.
