Electroless coating of Ni/Sn on Kevlar fiber and its metallization were operated.The surface appearance,com-position and phase of Kevlar fiber were investigated by means of SEM,EDS and XRD.The corrosion resistance,adhe-sion strength and electrical conductivity were also measured.The results showed that the pretreatment was necessary for getting clean,catalytic and favorable layer.The compact Ni-layer could be obtained by plating 120 min at pH value of 6 ,the adhesion strength was excellent and coating thickness reached 7 5 2 nm.The coating thickness of the compact Ni/Sn-layer obtained by plating 150 min at pH value of 0.8-1.2 was 1.4μm and combined well with Kevlar.The fibers of electroless Ni/Sn had a good corrosion resistance,adhesion strength and electrical conductivity,it could be well used for electronic component and electromagnetic shielding.
