Removal of Thermal Sprayed Layers

This paper deals with the removal of thermal sprayed coatings. It describes chemical, mechanical, thermal, and erosive and abrasive waterjet coating removal processes. Plain waterjet and cryogenic techniques reduce the risk of damaging the substrate or bond layers because they are more selective and precise. In cases where thermal induced diffusion processes have changed the bond characteristics between the coating and substrate, the use of selective mechanisms tends to be limited. Paper includes a German-language abstract.
