| Abstract: | This article analyzed the chemistry composition and metallography of the laval nozzle. The mechanism of corrosion failure was discussed in terms of CO_2 induce corrosion. The results indicated that the main reasons were using unsuitable materials and the CO_2 induce corrosion. Adopting other acceptable methods have got satisfactory results. |
