Tribopolymerization as an anti-wear mechanism. Quarterly progress report, July--September 1996
During this quarterly period, the author has made progress in a number of areas. He has continued to evaluate potential candidates for high load/high speed antiwear action using the approach of generating tribopolymers capable of withstanding high temperatures. Results are promising for ceramics as well as steel. The construction of a new instrument for high temperature studies of both liquid and vapor phase lubrication is almost complete. This will permit studies up to 350 C bulk temperature and considerably higher surface temperatures in controlled vapor-phase and liquid-phase studies. Selected monomers and monomer combinations found to be effective in hexadecane as a carrier fluid have also been tested in other fluids, including synthetic ester lubricant carriers. Additional studies using FTIRM for surface analysis of wear tracks have been made and are continuing. Further industrial contacts have been made to arrange for field testing of selected compounds as antiwear additives. The applications include the lubrication of 2-stroke and 4-stroke engines, machining and cutting, and fuel injector wear, particularly in gas (e.g., natural gas) engines.
