Abstract

According to the present invention there is provided a method of manufacturing a compound body having at least one, partly covering layer on a porous body, whose pore system is evacuate by means of a subpressure which is applied on the porous body by a suction cup or the like and the body is dipped in a slurry of powdery components of the layer. The compound body is densified by sintering or other heat treatment, e.g., post-HIP.
