Characterization and frictional behavior of nanostructured Ni-W-MoS2 composite coatings

Ni-W-MoS2 composite coatings were obtained by pulse plating from a Ni-W electrolyte containing suspended MoS2 particles. The coating composition, morphology, crystalline structure, microhardness and frictional behavior were studied as a function of MoS2 concentration. The results obtained in this st...
