摘要： Corrosion resistant multi-layered clad plates or sheets with high bonding strength is disclosed. According to the present invention, clad metals with high corrosion resistance such as Ti, Nb, V, or Zr and their alloys can be bonded with a cheap substrate such as Fe, Cu, or Ni and their alloys by the resistance seam welding. Using the insert metal causing the eutectic reaction, the clad metal can be strongly bonded with the substrate. Especially, corrosion resistant clad plates with excellent bonding strength can be fabricated by controlling the thickness and the microstructures of the eutectic reaction layer at the interface between the clad metal and the substrate or between the clad metal and the insert metal.

摘要： A NbSi2-base nanocomposite coating formed on the surface of niobium or niobium-base alloys is disclosed. The nanocomposite coating layer is manufactured by forming a niobium carbide layers or a niobium nitride layers by depositing of carbon or nitrogen on the surface, and then depositing silicon. The nanocomposite coating layer has a microstructure that SiC or Si3N4 particles are mostly precipitated on an equiaxed NbSi2 grain boundary. The thermal expansion coefficients of NbSi2-base nanocomposite coating layers become close to that of the substrates by adjusting the volume fraction of SiC or Si3N4 particles in the nanocomposite coating layers. Accordingly, the generation of cracks caused by thermal stress due to the mismatch in thermal expansion coefficient between the NbSi2-base nanocomposite coatings and the substrates can be suppressed, thereby improving the high-temperature oxidation resistance in the repeated thermal cycling use of the NbSi2-base nanocomposite coated substrates. Further, the increase in the volume fraction of dense SiO2 oxide phase formed on the surface of the NbSi2-base nanocomposite coating layers improves also high-temperature isothermal oxidation resistance.

摘要： The embodiments of the invention relate to a MoSi2-SiC nanocomposite coating layer formed on surfaces of refractory metals such as Mo, Nb, Ta, W and their alloys. The MoSi2-SiC nanocomposite coating layer is manufactured by forming a molybdenum carbide (MoC and MoC2) coating layers on the surfaces of the substrates at high temperature, and the subsequent vapor-deposition of Si. The MoSi2-SiC nanocomposite coating layer has a microstructure in which SiC particles are mostly located on the equiaxed MoSi2 grain boundary. The MoSi2-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.
