Abstract (en)

[origin: EP0335193A2] The invention relates to a process for the production of mouldings and structural elements, in which the substrate and a layer sprayed thereon are bonded to one another by the high-temperature isostatic moulding process and layers more than 5 mm thick are sprayed onto the substrate at a temperature of at least 600 DEG C by means of plasma spraying at a chamber pressure of 140 - 180 mbar, which is adjusted to at least 10<-><2> mbar after evacuation of the chamber , and the layer is bonded to the substrate diffusively and without pores by the high- temperature isostatic moulding process at at least 500 DEG C and at least 500 bar. <IMAGE>
