THE PREDICTION OF OXIDATION RATES OF CARBONACEOUS MATERIALS FROM PLASMA ARC TESTS 00.241,
Abstract
In the search for high temperature materials to withstand reentry conditions, a considerable amount of attention has been given to high temperature of sublimation, its superior materials. A set of equations was derived to account for surface recession rates due to oxidation and spalling, and a method was developed to derive the required material constants from plasma arc test results. Tests were restricted to reinforced carbonaceous material. It is believed, however, that the methods developed are applicable to any material which undergoes oxidation, and in which the chemical form is relatively independent of temperature. Matrix III, showed particular promise as an oxidation resistant material. This relies on an internally diffused coating, as opposed to a surface coating, and is therefore not liable to suffer catastrophic failure. (Author)
