Wet-chemical coating processes based on nanoparticulate zirconia materials hold great potential to become an energy and resource efficient alternative to conventional coating processes (e.g. physical vapor deposition). The challenge of this innovative coating technology is the requirement for a thermal post treatment of the coatings often applied on substrates with low thermal stability. Thus, the introduced laser-based process has considerable advantages over conventional oven processes that are not suitable for this purpose. It both enables short interaction times between the laser beam and the coated sample and therefore the necessary high peak temperatures in connection with short heat penetration depths.
