TLDR
In this article, the diffusion bondability of a superplastic Inconel 718SPF superalloy was enhanced by electroless nickel plating, and the bonding shear strength increased to 70.4 MPa for the same overlap length under the same bonding condition, regardless of the roughness of the surface to be bonded.Abstract:
Although intimate contact can be obtained for diffusion bonding of a superplastic Inconel 718SPF superalloy under a low pressure of 7 MPa, the precipitates formed at the interface retarded achievement of a sound joint. The shear strength was only 41.5 MPa for an overlap length of 12 T (T=1.3 mm, sheet thickness). The diffusion bondability of this Inconel 718SPF superalloy was enhanced by electroless nickel plating. In this situation, the bonding shear strength increased to 70.4 MPa for the same overlap length of 12 T under the same bonding condition, regardless of the roughness of the surface to be bonded. Upon decreasing the overlap length from 12 to 6 T, the bonding strength remained constant.read more
