Abstract

"The object of this investigation was to determine the effect of lubricant film thickness on the coefficient of friction and on the wear life of solid lubricants. Bonded molybdenum disulphide and bonded graphite were the lubricants tested. Dow Corning's LFW-1 and Falex lubricant tester were the two machines used for testing these lubricants. The lubricants were sprayed on the specimen surface. Pretreatment, spraying and curlng were done according to standard or manufacturer's recommended procedures. During the entire research, the procedure for experimentation was followed according to ASTM No. 2625 on Falex and CRC recommendations on LFW-1 machine. It was found that the film thickness lS an important factor in deciding performance of a solid lubricant. The coefficient of friction increases with increase in film thickness for thicknesses in the range tested (0.0017 in. to 0.0007 in.). For a maximum wear life, there is a definite optimum film thickness, above and below which the wear life decreases"--Abstract, page ii.
