| 中文摘要 | A multilayer CrAlN coating of Cr0.58Al0.42N/Cr0.84Al0.16N/Cr0.51Al0.49N has been fabricated by a reactive magnetron sputtering method. It consists of a bonding layer, a Cr-rich intermediate layer and an Al-rich outer layer. The multilayer structure provides the coating with good protection against different types of high temperature corrosion, i.e., high temperature oxidation and hot corrosion. The outer Al-rich layer gives the coating good oxidation resistance at 1000 and 1100 degrees C due to the formation of a continuous alumina scale. The parabolic rate constants of the coated samples decrease by about 2 orders of magnitude compared with that of the bare alloy samples. The intermediate Cr-rich layer can form a Cr2O3 scale to provide good protection under the,hot corrosion conditions in the Na2SO4 salt fluxing at 900, 950 and 1000 degrees C. The incubation period of the hot corrosion extends several times longer when the alloy was coated by the multilayer coating at the three selected temperatures. (c) 2007 Elsevier B.V.
