Burning of CP Titanium (Grade 2) in Oxygen-Enriched Atmospheres

Source

The flammability in oxygen-enriched atmospheres of commercially pure (CP) titanium rods as a function of diameter and test gas pressure was determined. Test samples of varying diameters were ignited at the bottom and burned upward in 70 % O2/balance N2 and in 99.5+ % O2 at various pressures. The burning rate of each ignited sample was determined by observing the apparent regression rate of the melting interface (RRMI) of the burning samples. The burning rate or RRMI increased with decreasing test sample diameter and with increasing test gas pressure and oxygen concentration. The oxygen concentration had a much more marked affect on the burning rate than oxygen pressure.
