Abstract
The aim of the present work is to study the effect of silicon dioxide and polytetrafluoroethylene (PTFE) additives on NiP coating performance under dry (unlubricated) conditions in unidirectional and reciprocating sliding modes in Ball-on-Flat configuration. Yttria-stabilized zirconia and chrome steel balls were used as counterbodies. Microstructural examination of specimens was conducted by a SEM with EDS. It was found that in contact with steel ball both additives were beneficial, while addition of SiO2 particles was detrimental for contact against ceramic ball. The highest improvement of tribological performance was obtained for NiP coated samples having PTFE or mixed additives.
