520 ‡aA pin-on-disk sliding friction apparatus was used to determine the effect of humidity and a wettability additive on boundary lubrication of steel in air and nitrogen with a polyphenyl ether. Poor wettability was observed for the ether in dry nitrogen from 150Oto 200' C (302' to 392' F) and high wear also occurred in this temperature range. The wettability additive improved the wetting and decreased wear of the ether in dry nitrogen. It increased wear in wet air and had little effect on wear in wet nitrogen and dry air. A relative humidity of 50 percent decreased wear in nitrogen and had little effect on wear in air.
