Abstract

Laser surface texturing (LST) is an emerging effective method for forming surfaces with specific parameters: optical, electrical, tribological, hydrophobic or hydrophilic and so on. The LST is laser parameters and overlap sensitive process. The new shifted LST is introduced, where heat load by laser picosecond pulses is decreased by specific schedule of scanning. Moreover, the shifted LST gives possibility to increase scanning repetition rate without heat accumulation effect. In this paper we have compared results of application classical methods of LST with shifted LST on stainless steel AISI 304L, 2017 aluminium alloy and nickel-based superalloy AM1.

Keywords: shifted LST, laser processing, laser high speed texturing, overcoming heat accumulation effect
