The surface of a part or product strongly influences its properties and functions. These are, e.g., abrasion and corrosion resistance, insensitivity to scratches, haptics as well as the visual impression to the customer. Therefore, many plastic parts have structured surfaces like leather textures on car dashboards. Usually these structures are integrated in the injection mould for the production of...
Laser micro polishing with pulsed laser radiation is a process to reduce the micro roughness of surfaces. During polishing the properties of the laser radiation have a great influence on the results.In this publication the influence of the type of intensity distribution (near-Gaussian, top-hat), of its geometry (circular, square), and of the pulse duration (≈100-1400ns) on the roughness of tool steel...
