The Pv product required for the frictional ignition of alloysNASA-White Sands has developed a frictional heating tester capable of evaluating the ignition properties of alloys in oxygen under friction conditions which involve rubbing. Sixteen alloys have been thus evaluated, yielding determinations of the product of the contact pressure and surface speed required for ignition in oxygen at 6.9 MPa; those which contained large Ni fractions manifested the greatest resistance to rubbing-induced ignition. The effect of the coefficient of friction is noted to be a major influence on ignition, and the results obtained indicate the value of frictional heating tests for environments involving frictional heating.
