PURPOSE: A manufacturing method of nano-colloid of iron-chromium - aluminum based alloy is provided to enhance static electricity spraying property by surface treating the surface of the nano-colloid. CONSTITUTION: A manufacturing method of nano-colloid of iron-chromium - aluminum based alloy comprises the following steps: coating organic compound on the surface of the nano-powder of Fe-Cr-Al based alloy(s10); and mixing the nano-powder with a dispersing agent in which organic compound is coated and a solvent and manufacturing colloid(s20). The Fe-Cr-Al based alloy power includes 82 weight% of Fe 82%, 6 weight% of Al and 12 weight% of Cr.
