Study on the Corrosion Productions Formed on the Surface of Lanthanum Hexaboride in the Sour Gas Environments
The corrosion behavior of lanthanum hexaboride (LaB6) in the environment containing H2S and CO2 was studied. The results show that the corrosion of LaB6 was severe when the environmental temperature and the partial pressure of H2S were high, and the corrosion would preferentially happen at the central part of the sample due to the lower compact of this part.
