Controlled-Impurity Helium Flow System

Location: 1038 Gerstacker

Figure shows the controlled-impurity helium flow system facility used to study the corrosion behavior of Ni-based superalloys in impure helium at temperatures up to 1000° C. It consists of a 3-zone tube furnace housing 7 quartz tubes, each of which can be supplied with a different gas mixture. Gas mixtures with controlled concentration levels of different gases are obtained by using premixed helium gas bottles and set of mass flow controllers. A discharge ionization detector gas chromatograph is used to analyze the gas mixture entering and exiting out of the furnace.
