Abstract

A novel composite coating containing WS2 in Ni-P matrix was obtained by electroless deposition route. The incorporation of tungsten sulfide particels enhanced the hardness and corrosion resistance of the Ni-P coatings. It was established that the electroless Ni-P-WS2 coating were able to sustain the low coefficients of friction under sever sliding condition in comparison with the Ni-P coatings. It is evident that the Ni-P_WS2 coatings have the option of being used as solid lubricants to the sliding parts of machinery in aerospace industries. The incorporation of WS2 and the existence of Ni3P in the matrix have been ascertained by XRD, SEM and AFM.
