Latest Patents
Jong-Kwon Lee holds a patent related to a MoSi-SiC nanocomposite coating layer. This invention pertains to a coating layer formed on surfaces of refractory metals such as molybdenum (Mo), niobium (Nb), tantalum (Ta), tungsten (W), and their alloys. The MoSi-SiC nanocomposite coating layer is manufactured by applying molybdenum carbide (MoC) coating layers at high temperatures, followed by the vapor deposition of silicon (Si). This innovative coating has a microstructure where silicon carbide (SiC) particles are predominantly located on the equiaxed MoSi grain boundary. By controlling the volume fraction of SiC particles, the thermal expansion coefficient of the coating can be closely matched to that of the substrate. This advancement helps suppress crack generation due to thermal expansion mismatches and improves both high-temperature cyclic oxidation resistance and low-temperature oxidation resistance of the coated substrate.
