Advanced coating substrate preparation by shifted and ultrafast laser texturing - ADVENTURE

Project summary

Thermal spray (TS) coating technology enables creation of functional surfaces with excellent properties for wide range of applications and products. Currently, grit blasting is standard for TS substrate preparation, but it is limited by low reproducibility, residues causing functional failure, substrate materials and production of dust. The ADVENTURE project aims to strengthen the TS technology by introducing laser surface texturing (LST) for substrate preparation as clean, flexible and reproducible method. The goals are up-scaling of LST method, development of innovative coating-substrate interfaces and functional testing in TS. Potential applications of the project results are in high added-value components, i.e., for space, aircraft, medical or power industry. Project´s impact will be high productivity and reliability of LST, improved adhesion, lifetime and reliability of coated parts, new coating possibilities and reduced dust pollution and grit material consumption.
