PLD from sector target can yield high smoothness/low friction DLC:Ag nanocomposites. Pulse excimer laser deposited DLC:Ag nanocomposites retain significant sp3%. Graphitization leads to residual stress/hardness/elastic modulus reduction. DLC:Ag8at.% nanocomposites, significantly enhance their tribological response. High levels of Ag-doping can lead to detrimental nanomechanical effects.
