Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung von Form­ teilen und Bauelementen, wobei der Grundkörper und eine darauf aufgespritzte Schicht mit dem Heiß-Isostatischen-Press-Verfahren miteinander verbunden werden und auf den Grundkörper bei einer Temperatur von mind. 6oo°C mittels Plasma-Spritzen bei enem Kammer­ druck von 14o - 18o mbar, welcher nach Evakuieren der Kammer auf mind. 1o⁻² mbar eingestellt ist, Schichten von mehr als 5mm Dicke aufgespritzt werden und die Schicht mit dem Grundkörper durch das HIP-Verfahren bei mind. 5oo°C und mind. 5oo bar diffusiv und porenfrei verbunden wird. The invention relates to a method for producing mold parts and components, the main body and one on it sprayed-on layer using the hot isostatic press process be connected to each other and to the main body at a Temperature of at least 6oo ° C by means of plasma spraying in a chamber pressure from 14o - 18o mbar, which after evacuating the chamber is set to at least 1o⁻² mbar, layers of more than 5mm Thickness can be sprayed on and the layer with the base body through the HIP process at least 5oo ° C and at least 5oo bar diffusive and is connected without pores.
