Abstract
Al O based layers having a total thickness of more than 0.3 mm are produced on a substrate by plasma jet spraying, said Al O based layers having a laminar sandwiched structure wherein at least one Al O layer is interpolated between two intermediate layers which are produced by plasma jet spraying as well, said intermediate layers consisting of a ceramic laminated material which is different from Al O and which on cooling increases in volume by phase transition. Preferred materials for said intermediate layers are Al O /ZrO , Al O /TiO , ZrO /Y O , Y O /ZrO , ZrO /MgO ZrO /CeO and ZrO /CaO alloy systems.
