Hot Corrosion of Plasma Sprayed Coatings for Waste Gas Turbine Blades

High temperature corrosion tests in 75%Na2SO4-25%. NaCl molten salt have been conducted on waspalloy specimens plasma sprayed with Co-Cr-B-Si, Ni-Cr-B-Si-hCr3C2, X-40, X-40 + TiC and Ni/Al + Al2O3 coatings, test coupons were exposed isothermally at 750℃up to 200 h. After the corrosion tests, each sample was examined by OM, SEM and EMPA. It was found that X-40, X-40 + TiC and Ni/Al + Al2O3 were violently corroded by the molten salt due to cracking and spalling of the coatings, whereas the Co-Cr-B-Si and Ni-Cr-B-Si + Cr3C2 exhibited superior corrosion resistance, which were thought to be related to the formation of chromium and silicon oxide film. A possible corrosion mechanism had been proposed and it is suggested that the excellent corrosion resistance and high hot-hardness of the two B-Si containing coatings may be of significance for applications in petroleum refining industry as protective coatings of power generating turbine blades which are used under severe corrosion/erosion conditions.     

Reed-Solomon码的符号级软判决译码算法

为了在译码性能和复杂度之间获得更好的折中,提出两种Reed-Solomon码的符号级软判决译码算法:一种将置信度排序译码集成到Chase译码的组合译码算法;另一种则采用逐级选择测试序列集的广义Chase-2译码算法。二者在一定的场合能够充分利用软判决信息。仿真结果表明,第一种算法在译码复杂度较低时,能够获得很好的综合性能;而第二种算法则具有很好的灵活性,且在译码复杂度可接受的范围内具有很好的综合性能。两种算法在一些场合中都能获得比目前其它一些常用的符号级软判决译码算法更好的综合性能。
