Green tribology

  1. 1. • PRESENTED BY - SUMIT CHOUDHARY “green-tribology” A SEMINAR PRESENTATION ON
  2. 2. PRINCIPLES OF GREEN-TRIBOLOGY • Minimum of heat & energy dissipation • Minimum of wear • Self-lubrication • Bio-degradable lubrication • Using sustainable engineering principles • surface texturing • environmental implications of coatings • real-time monitoring • design for degradation • sustainable energy applications • Bio-mimetic approaches
  3. 3. AREAS OF GREEN-TRIBOLOGY Environment- friendly lubrication The tribology of renewable energy application. Biomimetics for tribological applications
  4. 4. Biomimetic Surfaces • application of biological methods and systems found in nature to the study and design of engineering systems and modern technology. • 1. The lotus effect based non-adhesive surfaces.
  5. 5. The Gecko effect • Complex hierarchical structure of gecko feet surface. reversible adhesion…
  6. 6. shark-skin effect • Biofouling and biofilming • Conventional antifouling coatings for ship hulls are often toxic and environmentally hazardous • Oleophobic surfaces capable of repelling organic liquids • Microstructured surfaces for various optical applications
  7. 7. Microtextured surfaces for de-icing and anti-icing • Anti-icing is accomplished by applying a protective layer of a viscous anti-ice fluid • water repellent surface can also have de-icing properties • propylene glycol or ethylene glycol, can be toxic
  8. 8. Composite and nanocomposite materials • self-cleaning, self-lubrication, and self-healing • Metal-matrix composites, and polymeric composites as well as ceramics (including concrete) have been recently used for this purpose.
  9. 9. Biodegradable Lubrication, Coatings, and Materials • The use of natural biodegradable lubricants • Chemical modification of vegetable oils and/or the use of antioxidants • Ionic liquids for green molecular lubrication. • Powder lubricants and,in particular, boric acid lubricants
  10. 10. Renewable Energy • The tribology of renewable sources of energy is a relatively new field of tribology. • environmentally friendly energy production. • Can be used in Wind power turbines, Tidal power turbines, Geothermal energy plants.
