Strengthening Corrosion and Protection of High Temperature Structural Materials

<p>High-temperature structural materials are characterized by their high melting point high-strength and high-temperature creep resistance low thermal expansion coefficient and excellent corrosion resistance. Such materials are widely used in metallurgy chemical applications aerospace nuclear reactors and other situations where extreme environments are encountered. During high-temperature service high-temperature structural materials are exposed to extremely harsh high-temperature environments bear mechanical and thermal loads and are exposed to high-temperature oxidation erosion corrosion etc. Therefore high stress can be easily concentrated at a defect site especially near the phase interface. Thermal expansion stress will drive the nucleation and propagation of cracks. At the same time friction oxidation and corrosion will also aggravate crack propagation and material failure which will pose a catastrophic threat to high-temperature components. Therefore the characterization understanding strengthening and corrosion protection of high-temperature structural materials are very important. This Special Issue focuses on second phase enhancement surface coating technology high-temperature corrosion wear erosion and protection with respect to high-temperature structural materials.</p>
