| Abstract Scope |
Surface tension is an important property for heat and mass transfer modeling of several industrial processes, including casting of jet engine turbine blades, welding of nuclear reactor containers, and crystal growth of semiconductors. The surface tension of molten metals is affected by even a small amount of adsorption of surface active elements such as oxygen.
The NASA Marshall Space Flight Center’s electrostatic levitation (ESL) laboratory has a system that allows the oxygen partial pressure within the levitation chamber to be measured and controlled over a wide range.
The surface tension of molten Inconel 718 was measured at several oxygen partial pressures using the oscillating drop method, and the results will be presented. |
