Latest Patents

Keun-Hyung Son holds a patent for a MoSi-SiC nanocomposite coating layer. This invention relates to a coating formed on surfaces of refractory metals such as molybdenum (Mo), niobium (Nb), tantalum (Ta), tungsten (W), and their alloys. The coating is manufactured by applying molybdenum carbide (MoC) layers at high temperatures, followed by vapor-deposition of silicon (Si). The resulting nanocomposite coating exhibits a microstructure where silicon carbide (SiC) particles are predominantly located at the MoSi grain boundaries. This innovative coating can be engineered to have a thermal expansion coefficient closely matching that of the substrate, thereby reducing the risk of cracks due to thermal expansion mismatches. The coated substrates demonstrate improved resistance to high-temperature cyclic oxidation and low-temperature oxidation.
