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 X-ray diffraction patterns and STEM-EDX, microstructure of the starting materials and the composite layer was observed. Nickel phase was distributed homogeneously in alumina phase. Moreover, we discussed the effect of nickel / alumina ratio on the resistance to friction as the mechanical property of the composite layer.
