Static friction tests with special lubricants

STATIC friction tests of a number of relatively new special lubricants, in combination with various metals, have recently been completed at the National Bureau of Standards. Selection of a lubricant for a particular special application was the immediate goal of the investigations, which were sponsored by the Naval Ordnance Laboratory and conducted by H. S. White of the NBS engines and lubrication section. Although lubricant information was the primary concern of the tests, the effect of metal composition and of metal surface finish on static friction was also investigated.
