Coating technology - thermal spraying and PVD

In this specialist group, current issues and projects in the field of coating technology are investigated. The focus is on the application of coatings ranging from the sub-micrometer range (PVD) to several millimeters in thickness (thermal spraying). Typical applications include wear and corrosion protection coatings, as well as the development of functional layers such as fluid-permeable layers. Another focus is on the development of hybrid technologies, where, for example, soldering is combined with thermal spraying. Intensive research is also being conducted on the transplantation of coatings. The basic idea of this transplantation process is that it is not the component that is coated, but a negative mold, such as an insert in a die-casting mold, and then the layer is transferred to the actual component. Currently, the focus is particularly on the aluminum die-casting process in this context.
