Please read the entire fucking sentence you reply to. Their attempt at expander cycle couldn't maintain the needed pressures. Corrosion was actually a secondary problem by comparison.

From the paper:
>Isp values range between:
> • 250 seconds for sustainable cladding surface temperature (1400 K) and bleed cycle
> • 315 seconds for maximum cladding surface temperature (2400 K) and expander cycle
>Multistage pump systems (up to 7 stages to prevent cavitation) for expander cycles are required depending on thrust and surface temperature criteria. This results in pressures as high as 700 atm and a bleed cycle would be more feasible.
