Projects and Products

The substitution of the conventional spray powders by suspensions offers new possibilities, such as the direct use of finely dispersed powders, and thus saving in the production of specific thermal spraying feedstock powder, and the production of nanostructured coatings.

Insulating coating, conductive heater and cover coating can be freely selected, which provides numerous opportunities for heating and tempering applications.

Therefore concepts to measure the coating thickness during the process without the need for physical contact are of crucial importance to the cost effectiveness of thermal spraying solutions.

Thermally sprayed hard metal coatings have been mainly applied as protective barriers against abrasion, erosion, friction and sliding wear. The use of modern spray technologies has the potential to extend the performance limits of these coatings and thus allow the production of novel coatings for application in components subjected to high stress.

The goal of the BMBF funded project is the development of a thermally sprayed based manufacturing technology, which allows the production of efficient and stable thermoelectric module components to be applied between 400 and 800°C.

Although thermally sprayed coatings in the system Cr2O3-TiO2 have a high potential, this system has been, till date, scarcely used.
