Friction-induced ignition of metals in high-pressure oxygenData are presented on friction-induced metal ignition (such as occurring as a result of the possible rubbing of oxygen-pressurized hydrostatic bearings and turbine blade tips) in a high-presure oxygen environment. Friction heating tests were carried out at oxygen pressures from 1 to 300 atm and surface speeds from 10 to 33 m/sec, using the NASA/White Sands Test Facility. Test results are presented on the rubbing of like material pairs spanning a wide range of burn factors and on that of dissimilar metal pairs having significantly different burn factors, indicating that the burn factor is a suitable index for rank ordering in ignition resistance for the most, but not all, materials.
