Abstract : The areas where resin bonded solid film lubricants are deficient were studied. These areas were, (1) finite wear, (2) ineffectiveness caused by contamination by conventional lubricants, and (3) decreased corrosion protection under dynamic conditions. The following conclusions may be derived from the data obtained. A resin bonded solid lubricant coating containing MoS2 whose particle size is less than 0.5 microns, when vacuum impregnated into a porous bearing material, increased wear life by a factor of seven, as compared to standard application techniques. The ineffective lubrication by bonded solid film lubricants when contaminated by conventional lubricants was not remedied by making it more difficult for the oil to penetrate the coating. The corrosion preventive properties of the bonded solid film lubricant coating, tested under dynamic conditions, was greatly improved by increasing the coating thickness. (Author)
