Laser Process Enables Micro-structural Control of Metals

摘要

Thin-film coating developer Picodeon Ltd. Oy (II, Finland) has developed an ultra-short pulsed laser deposition (USPLD) surface coating technology that can create either porous or dense aluminium oxide (Al_2O_3) coatings on heat-sensitive substrates for use in a wide range of industrial applications. Porous Al_2O_3 layers are used as filters and electrical insulation layers, while dense Al_2O_3 is used as a barrier layer and as an excellent optical coating with high transmittance properties. The Picodeon process enables precise micro-structural control of Al_2O_3 coating characteristics with management and maintenance of coating process parameters on Picode-on's Coldab Series4 USPLD batch-process coating equipment.
