Highest work of adhesion
Compared to Cr₂N, the CrN interface with Ag-based filler metal exhibits stronger bonding and less tendency for microcracks, making it a more reliable brazing interface phase.

The Ag(111)/CrN(111) B-site interface has the largest work of adhesion
The Ag–N chemical bond strength at the Ag(111)/CrN(111) interface is stronger than at the Ag(111)/Cr₂N(0001) interface
The Cr₂N phase is more likely to produce microcracks in brazing joints
