In March 2020, our LASOX-COAT® selective coating was registered in the European patent register by the European Patent Office under European patent no. 2853616, and is therefore legally effective.
LASOX-COAT® is an innovative process for the production of wear and/or corrosion-resistant oxide layers on aluminum and titanium. What is special about the process is the use of a laser. Pointed at the surface of the workpiece to be coated in an oxygen atmosphere, it treats the surface lane by lane. Consequently, the process does not require the use of any chemicals. The laser causes the material elements on the aluminum surface of the workpiece to be treated to melt and evaporate, which results in the creation of an aluminum oxide conversion layer.
Depending on the selected process parameters, it is possible to influence the layer thickness and the degree of roughness. The simultaneous use of several laser beams can accelerate the coating process in a proportionate manner. Using this selective coating process, it is also possible to create letterings, individual lines or complex shapes and patterns. LASOX-COAT® can in fact be used on almost all aluminum alloys and titanium.
