Abstract:

The seizure of threaded connections and other tight fits was found to result from galling of the contacting surfaces. A quantitative method was developed for measuring the galling characteristics of standard metal surfaces under controlled conditions. Anti-seize compounds can be evaluated by observing their effect on these measured characteristics. A seizure tester was designed and constructed which automatically records galling test data and can be used for rapid routing testing. Metal specimens which are used with this machine can be 1 assembled with an anti-seize compound between the test surfaces, 2 exposed to conditions simulating specific applications, and then 3 tested for seizure. The results of seizure tests made with several commercial anti-seize compounds are included. A preliminary correlation was obtained between these testing procedures and other performance ratings. It is concluded that this basic test method can be used to evaluate anti-seize compounds for 1 High temperature service 1200 - 2000 F, 2 Aircraft oxygen system service, 3 Liquid oxygen system service, and 4 Similar specific applications.
