“…9b) as well as the changes observed in sample Ag13 suggest that silver is segregating in the coating surface. The surface segregation of Ag has been reported by several authors; however this process occurred at higher temperatures [35,37,38,39,40]. The surface segregation of silver is attributed to the low miscibility of this noble metal in different coatings [37] associated with the reduction in the system surface energy, which drives the segregation process.…”

The surface segregation of silver is attributed to the low miscibility of this noble metal in different coatings [37] associated with the reduction in the system surface energy, which drives the segregation process. In the case of DLC matrix it seems that surface segregation occurs even at room temperature, however a more detailed study of this topic is needed in order to better understand the stability of Ag-DLC system.…”

“…The lifetime of a nanocomposite YSZ ± Ag ± Mo coating was even more prolonged after applying the TiN surface porous mask [112]. This approach made it possible to confine the transfer of lubricating silver into a coating surface and thereby to reduce the rate of its depletion at high temperatures.…”

“…It was shown in Ref. [112] that a rise in Ag content up to 24 at.% allowed the friction coefficient to be reduced from $ 0X8 to even $ 0X24; however, the lifespan of the resultant coating did not exceed 4500 cycles (Fig. 9d).…”
