- Abstract
- The objective of this program was to determine the relative ignition and combustibility characteristics of titanium alloys. Nine titanium alloys and two coatings were subjected to a laser ignition source at each of two conditions of temperature, pressure, and airstream velocity typical of gas turbine engine compressor environments. Three of the alloys did not burn and no significant difference could be established in the burning characteristics of six of the alloys. A chromium-molybdenum coating significantly reduced the magnitude of burn and an ion vapor deposited aluminum coating prevented ignition. The higher temperature environment was shown to produce a more severe burn. Comparison of one test run with results predicted by the analytical model currently under development showed good agreement.
