Micro-textured Engineered Surfaces

Micro-textured Engineered Surfaces

• Specific Challenge
• REDUCE ENERGY LOSSES DUE TO FRICTION AND WEAR
  (including losses in manufacturing processes,
  machines and systems)
• It is estimated that 1/3 of the energy produced
  in the world is consumed to overcome friction
• Even moderate friction reduction could result in
  very significant energy conservation
• Idea for Meeting the Challenge
• MANUFACTURING METHODS THAT ALLOW THE GENERATION
  OF ENGINEERED SURFACES WITH PRESCRIBED
  TOPOGRAPHIES AND FRICTION PROPERTIES
• Traditional friction reduction methods, i.e.,
  polishing, grinding, low friction coatings,
  lubricants, etc. are limited in their ability to
  precisely control the behavior of surfaces in
  contact
• Lack of full understanding of the physics of
  contacting surfaces
• Approach
• DEVELOP MICRO-TEXTURING PROCESSES IN COMBINATION
  WITH NON-GEOMETRIC SURFACE MODIFICATION METHODS
  TO CONTROL FRICTION/WEAR BEHAVIOR
• Example Laser texturing in combination with
  laser-assisted chemical modification
• Roll-forming with rolls with micro-features to
  achieve high production throughput, etc.
• What is the Manufacturing Challenge
• NEW HYBRID TEXTURING PROCESSES
• FUNDAMENTAL UNDERSTANDING OF ENERGY DISSIPATION
  IN CONTACING SURFACES
• THE SCIENCE OF SURFACE ENGINEERING
