- Additional information
- The paper has made both scientific and technological impacts. Laser textured surfaces reduce boundary friction and improve energy efficiency of poorly lubricated sliding contacts. However, the exact underlying mechanism (scientific) was not established, nor the optimisation of individual texture shape, pattern and distribution (technological). The paper addressed both these issues with integrated precision tribometry and micro-hydrodynamic analysis, showing 1-4% energy gain in conditions corresponding to piston-cylinder interactions in race engines. The research was funded by the EPSRC (program grant Encyclopaedic, EP/G012334/1). The findings have resulted in new measurement infrastructure and a new range of advanced cylinder liners at Capricorn Automotive.
