✦ Synopsis

The effects of S impurities, both interstitial and substitutional, on adhesions at Al 2 O 3 /Ni and ZrO 2 /Ni interfaces were investigated with the first-principles method. The effects of S impurities on the adhesion of the Ni/Al 2 O 3 interfaces are quite obvious, and changes in equilibrium adhesive energies evidently range with the type of impurities. The effects of S impurities on the adhesion of the Ni/ZrO 2 interface are very slight. For the two interfaces considered, both interstitial and substitutional S impurities will increase their equilibrium interfacial distances.
