  1. Tribology of Engine Cylinder Kits. Demands for increased power density and durability and lower oil consumption have resulted in a need for cylinder kits with enhanced scuff and wear resistance. Specific research topics include: simulation of liner/ring wear, effect of cylinder wall surface topography on cylinder kit wear and scuffing, theoretical prediction of oil film thickness between piston rings and cylinder walls and use of advanced materials and coatings to enhance tribological performance.
  2. Engine Valve Wear. Primary goals are to characterize and simulate valve wear mechanisms which occur on engine valves. The laboratory simulator which has resulted from this work is being used to rank the wear resistance of various valve materials and processing methods.
  3. Effects of Tool Wear on the Surface Topography of Machined Surfaces. The effect of tool wear on the surface topography of turned work pieces has been studied. A physical model which describes this relationship has been determined and future work will likely concentrate on developing non-contacting methods of monitoring work piece surface topography to help provide on-line optimization of metal cutting.
  4. Vibratory Stress Relief. Vibratory Stress relief (VSR) is being investigated as an alternative to tempering. VSR is expected to be more economical, faster and cleaner than tempering. Welded, cast, plastically deformed and heat treated samples are being investigated.
