Abstract
The present invention relates to a composite layer including a metal and inorganic powders, and a method for manufacturing the same. The method for manufacturing a composite layer including a metal and inorganic powders includes step of preparing an electrolyte which includes nickel sulfamate [Ni(NH2SO4)] at 50.0 g/l˜300.0 g/l, boric acid at 10.0 g/l˜20.0 g/l, nickel chloride (NiCl2) at 1.0 g/l˜10.0 g/l, coumarin (C9H6O2) at 0.02 g/l˜0.5 g/l, sodium dodecyl sulfate [CH3—(CH2)11—OSONa] at 4.0 g/l˜60.0 g/l, sulfuric acid at 0.0 ml/l˜150.0 ml/l, one or more inorganic powders selected from the group of alumina (Al2O3) and silicon carbide (SiC) at 20.0 g/l˜70.0 g/l, and the remainder being distilled water. A basic metal to be coated with the composite metal is dipped into the electrolyte, and power is applied to the basic metal to electroplate the basic metal with the electrolyte to form a composite layer on the basic metal.
