Abstract

In this paper, the protective electroless Ni-P/SiO2 on iron substrate were successfully prepared. The prepared Ni-P/SiO2 electroless composite coating were characterized for morphology, microstructure. The anticorrosion properties of the Ni-P/SiO2 coating in 10wt.% HCl solution were evaluated by immersion tests, SEM and EDS at ambiance temperature. The results revealed that the SiO2 concentration in the bath and heat treatment can influence the corrosion protection performance of electroless deposited Ni-P/SiO2 coatings. The corrosion resistance of Ni-P/SiO2 coating increases initially and decreases afterwards with the sustained increasing of immersion time in HCl solution. The Ni-P/SiO2 electroless composite coating can afford better corrosion protection for magnesium alloy substrate compared with Ni-P coating
