Diffusion bonding of mismatch dental alloys
The diffusion bonding of Ti‐6Al‐4V and Co‐Cr‐Mo dental alloys has been investigated in terms of the atoms diffusion, the microstructure evolution, and the bonding strength. The bonding performance reveals asymmetry diffusion profiles for both the Co and Cr in Ti‐6Al‐4V and the Ti in Co‐Cr‐Mo alloy....

| description | The diffusion bonding of Ti‐6Al‐4V and Co‐Cr‐Mo dental alloys has been investigated in terms of the atoms diffusion, the microstructure evolution, and the bonding strength. The bonding performance reveals asymmetry diffusion profiles for both the Co and Cr in Ti‐6Al‐4V and the Ti in Co‐Cr‐Mo alloy. Their diffusion coefficients (Arrhenius relations) have been established based on the experiments. Co and Cr diffusion into Ti‐6Al‐4V leads to alpha → beta transformation and the intermetallics‐formation. Maximum bonding strength occurs at about 840°C. The bonding joint fails under the shear stress in the Ti‐6Al‐4V side near the bonding interface in brittle manner. The intermetallics in the diffusion layer together with the unbonded areas and other flaws in the bonding interface are responsible for the shear brittle fracture, which also weaken the bonding strength. © 2009 Wiley Periodicals, Inc.
