Abstract

Ternary iron-tungsten-phosphorus (Fe-W-P) coatings were electrodeposited with different sodium tungstate (NaWO4 center dot 2H(2)O) concentration on stainless steel 316 L substrate. These coatings were characterized by energy dispersive X-ray spectrometer (EDX), scanning electron microscope (SEM), and X-ray diffraction (XRD). The friction and wear behavior of these coatings were investigated using ball-on-disk tribometer under dry conditions. This study reveals a nanocrystalline and. nodular structure with nanometric grain size of the deposited alloy. The maximum level of incorporation of tungsten (W) is about 29.54 at %, It was obtained with 0.5M of sodium tungstate concentration, and it increases the microhardness of the coatings. Moreover, it was found that Fe-W-P coatings had significantly improved the tribological properties of the substrate due to their higher wear resistance and lower friction coefficient.
