Surface engineering by plasma techniques, ionic sources, and laser beams

PAVET Project (2002 - 2003)
Coordination by LTFN
AUTh Sci. Responsible: Prof. S. Logothetidis

The aim of this project is the development of a new, more accurate process of forming the razor edge, which will be incorporated to the production process right after the stage of razor's forming with grinding wheels.
Available techniques, capable of controlling the forming of the razor edge with high precision (several hundred nm) are :

  • Ion Beam Bombardment (IBB) by using Kauffman sources,
  • RF Plasma Etching (RFPE),
  • Pulse-DC Plasma Etching (PDCPE), and
  • Laser Micromachining(LM)

The project's target is to investigate the capability of the above techniques to form the edge of the razor blades with an accuracy of several hundred nm and to find the optimum operation conditions for each one of them, in order to choose one, that could be productively applied in an intermediate stage of the current production process.
