“…Liang and Xie [23] developed a friction and spray electroplating technique which combined the merits of diamond block rubbing and jetting, and achieved a fast electrodeposition of bulk nickel coatings. Ning and He [24] put forward a mechanical attrition (MA) method by the vertical movement of glass balls with a special vibrating frequency on the sample surface, which changed the grain growth direction and microstructure of nickel coatings. Zhu et al [25] reported that nanocrystalline nickel grain sizes of 30-80 nm can be prepared by an electrodeposition method in combination with the simultaneous polishing of free particles.…”

“…Figure 1c,d show the SEM image of the surface of the Ni metallization layer by electro and electroless plating, respectively. The electroplated Ni layer had a pyramid-like crystal morphology, which is generally observed [23]. On the other hand, the Ni–P electroless plating layer had a smoother surface than the Ni electroplating layer.…”

The thermal cycling life of direct bonded aluminum (DBA) and active metal brazing (AMB) substrates with two types of plating—Ni electroplating and Ni–P electroless plating—was evaluated by thermal shock tests between −50 and 250 °C. AMB substrates with Al2O3 and AlN fractured only after 10 cycles, but with Si3N4 ceramic, they retained good thermal stability even beyond 1000 cycles, regardless of the metallization type. The Ni layer on the surviving AMB substrates with Si3N4 was not damaged, while a crack occurred in the Ni–P layer. For DBA substrates, fracture did not occur up to 1000 cycles for all kind of ceramics. On the other hand, the Ni–P layer was roughened and cracked according to the severe deformation of the aluminum layer, while the Ni layer was not damaged after thermal shock tests. In addition, the deformation mechanism of an Al plate on a ceramic substrate was investigated both by microstructural observation and finite element method (FEM) simulation, which confirmed that grain boundary sliding was a key factor in the severe deformation of the Al layer that resulted in the cracking of the Ni–P layer. The fracture suppression in the Ni layer on DBA/AMB substrates can be attributed to its ductility and higher strength compared with those of Ni–P plating.
