| Abstract Scope |
This study evaluates the use of Vacuum Hot Pressing (VHP), Hot Isostatic Pressing (HIP), and a combination of both methods for diffusion bonding sintered cemented carbide to Fernico 1 or steel. The results show that, by employing a suitable interlayer between the cemented carbide and the metal, it is possible to completely avoid decarburization and eta-phase formation, both of which are critical to achieving optimal bond strength.
Residual stresses are significantly reduced when using Fernico 1, a low thermal expansion alloy as a substrate which is better matched to the cemented carbide. The strength of the bond is excellent when using Fernico 1. Overall, the findings indicate that diffusion bonding is not only a viable alternative to brazing but often a superior method for attaching sintered cemented carbide to surfaces used in wear protection applications. |
