Abstract
Coating of nickel/alumina composite layer by Aerosol Deposition Method was investigated. Nickel/alumina ratio was controlled by initial amount of nickel and milling time. By scanning electron microscopy, microstructure of the composite layer was observed. Nickel phase was distributed homogeneously in alumina phase. Moreover, we discussed the effect of nickel/alumina ratio on the mechanical and electrical properties of the composite layer.
