Laser surface texturing with shifted method—Functional surfaces at high speed

Popis výsledku v původním jazyce

Laser surface texturing is a promising technology for future wide application of functional surfaces with specific properties like hydrophobic, antibacterial, adhesive, 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 ultrashort pulsed lasers in last years did not dramatically increase productivity, because there are physical limitations of current processing 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). 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. In the present work the principle and advantages of the method are described. The results of the method are compared with two standard methods (path filling of objects and hatch over all objects). The sLST method is presented in both single pulse and burst variants. Examples of its application on different materials for increased adhesion of surface coatings are shown.
