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(NHSO)] at 50.0 g/l&#x2dc;300.0 g/l, boric acid at 10.0 g/l&#x2dc;20.0 g/l, nickel chloride (NiCl) at 1.0 g/l&#x2dc;10.0 g/l, coumarin (CHO) at 0.02 g/l&#x2dc;0.5 g/l, sodium dodecyl sulfate [CH&#x2014;(CH)&#x2014;OSONa] at 4.0 g/l&#x2dc;60.0 g/l, sulfuric acid at 0.0 ml/l&#x2dc;150.0 ml/l, one or more inorganic powders selected from the group of alumina (AlO) and silicon carbide (SiC) at 20.0 g/l&#x2dc;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.

The embodiments of the invention relate to a MoSi-SiC nanocomposite coating layer formed on surfaces of refractory metals such as Mo, Nb, Ta, W and their alloys. The MoSi-SiC nanocomposite coating layer is manufactured by forming a molybdenum carbide (MoC and MoC) coating layers on the surfaces of the substrates at high temperature, and the subsequent vapor-deposition of Si. The MoSi-SiC nanocomposite coating layer has a microstructure in which SiC particles are mostly located on the equiaxed MoSigrain boundary. The MoSi-SiC nanocomposite coating layer can have a close thermal expansion coefficient to that of the substrate by controlling a volume fraction of SiC particles exisiting in the nanocomposite coating. As a result, the generation of cracks due to the mismatch in the thermal expansion coefficients between the substrate and the nanocomposite coating layer is suppressed and the high-temperature repeated thermal cyclic oxidation resistance and the low-temperature oxidation resistance of the coated substrate are improved.
