New laser surface texturing method enabling high processing speeds

Popis výsledku v původním jazyce

Laser surface texturing is a promising technology for future wide application of functional sur-faces with specific properties like hydrophobic/hydrophilic, antibacterial, antisticking/bonding, selfcleaning, anticorrosion, light absorbing, low friction, etc. Great advancements have been made in this field in last years, but in most cases it takes from minutes up to one hour to produce one square centimetre of a functional surface. Even availability of high power pulsed lasers in last years did not dramatically increase productivity, because there are physical limitations of current pro-cessing methods: heat accumulation and oxidation, plasma shielding effect and precision at high speeds. In order to solve these limitations, there have been developed a new method called shifted laser surface texturing method (sLST). In the present work we describe the principle of the method and show comparisons of texturing results with standard methods. The new method has a potential to be at least 100 times more productive with no heat accumulation effect and virtually unlimited number of complex shape objects produced with high precision on surface.
