The Effects of Agitation on the Properties of Antifriction Ni-P-MoS2 Composite Coatings
Authors
Abstract
In this work the effects of various methods of agitation on the properties of electroless Ni-P-MoS2 composite coatings were investigated. Magnetic stirring as well as purging the solution with gas (Air, Oxygen, Nitrogen) were used. Plating rate, chemical composition, MoS2 distribution, and hardness of the deposit were measured. Topography of coating was studied with metallography and scanning electron microscopy. It was concluded that purging the solution with air produced optimum results, i.e. high rate of deposition, uniform distribution of MoS2 particles and appropriate surface morphology.
