In an effort to examine the potential of salt to damage a TiAl alloy (nominal composition in at%, Ti-48Al-2Cr-2Nb), in conditions relevant to heat engines, the alloy was subjected to hot corrosion by application of simulated sea salt by aqueous means. Bare ground specimens were sprayed with seawater solution, dried, and exposed in an air furnace at 760$\sp\circ$C for times between 0.1 and 20 ks. Obvious attack occurred in as little as 0.3ks in regions where salt was deposited. In such regions, oxide growth was accelerated and non-adhesive. Regions below accelerated growth were pitted heterogeneously in a manner that indicated the alpha-2 phase was preferentially attacked, particularly in lamellar regions. Mechanical strength was measured by four-point bending testing. A reduction of fracture strength was observed only for specimens with the longest exposure. Pre-oxidized specimens were exposed to a salt fog and then a heat cycle. Accelerated oxide growth was observed after numerous salt application and heat cycles for short pre-oxidation times (3.6 ks) but not for longer pre-oxidation times (360 ks). Intermittent weight gain was measured for short pre-oxidation times (3.6 ks). EDS was used to analyze elemental concentrations on surfaces of all specimens. DTA analysis of salt/TiAl mixtures in N$\sb2$ indicate that endothermic reactions occur around 700$\sp\circ$C. X-ray diffraction was used to determine the products of the above reactions.

为了测试盐对钛铝合金的潜在损害（公称成分百分含量，Ti-48Al-2Cr-2Nb），在和热机相关的条件下，我们应用水中模拟的海盐让合金进行热腐蚀。裸露的地面标本被喷上海水溶液，风干，然后放入760$\sp\circ$C的热风炉中历时0.1到20ks。在0.3ks时就开始在盐附着的区域出现明显的腐蚀。这些地方的氧化物生长速度加快，并且它是非粘性的。快速氧化层下面的区域是多相的，显示出阿尔法-2相更易被腐蚀，特别是在薄层区。我们使用四点弯曲测试来测量样品的机械性能。只在接触时间最长的样品上才发现断裂强度降低的现象。预氧化处理的样品与盐雾接触然后经过加热过程。在无数次的应用盐雾和加热周期后，我们观测到短期预氧化处理的样品（3.6ks）有氧化物的加速生成的现象，而长期预氧化处理的样品（360ks）没有。对短期预氧化处理的样品（3.6ks）间歇性地测量了它的增重。使用能谱仪来分析所有样品表面的元素浓度。对N$\sb2$的盐/钛铝合金混合物的差热分析表明在700$\sp\circ$C附近产生了吸热反应。另外使用了x射线衍射法来确定上述反应的产物。

化学专业术语可以找专门的机构帮忙，我知道清北医学翻译在做这个，挺不错的，去年在他们那边翻译了一篇化学论文。价格也不是很贵。
