Lubricant Friction and Durability Tests under Simulated Weapon Conditions

Abstract

Lubricant friction and durability tests were carried out on four lubricants: VV-L-800A(PL-S), MIL-L-14107B(LAW), MIL-L-46000A(LSA), and MIL-L- 46150(LSA-T). The tests were conducted on the USAWECOM Friction and Wear Tester, a reciprocating motion machine in which weapon action is simulated. In this test, AISI 4340 steel with a manganese phosphate finish was used. Test loads varied from 37 to 312 pounds or from 62 to 473 pounds per square inch. Dynamic friction coefficients obtained during operation at loads of 312 pounds were: PL-S, 0.15; LSA, 0.10; and LSA-T, 0.08. The LAW could not support the 312-pound load; its friction coefficient increased with increasing load. Lubricant durabilities were in the order LSA-T>LSA>PL-S>LAW. These results show a correlation with weapon tests.
