Composite iron deposits containing non-conductivite Si particles and conductive Si-Fe alloy particleswith an average size of 1μm were prepared in circulating solution, the effects of particle conductivityon the co-deposition process of particles were investigated. The results show that high conductivitycontributed to the co-deposition process of particles into the composite coatings, and in a mode of"cladding" for the co-deposition of conductive Si-Fe particles, while that for non-conductive Siparticles was "embedding" mode. At the same time, with increasing the conductivity, the co-depositionprocess of particles was obviously deviate from the Guglielmi model. A possible mechanism on theforming process was discussed.
