This seminar will focus on metal patterning for surface engineering based on structures ranging from few nanometres to millimetres in size. We will limit our purpose to plasma, electron and ion beam patterning techniques.In the first part of this presentation, the results reported in the literature will be reviewed. The second part of this presentation will concern the new technique we developed in our institute. This new concept of surface patterning belongs to the third category of this classification. It is applicable to austenitic materials forming the so called "expanded austenite phase". The redistribution of material from some parts of the surface to others is based on a selective plasma assisted diffusion treatment of stainless steel substrates masked by TEM grids of different mesh side.
