Method for manufacturing a metal-ceramic composite structure and metal-ceramic composite structure
The invention relates to a method for manufacturing a metal-ceramic composite structure (20) intended to be exposed to high temperatures, comprising a base metal structure or component (19), which is on at least one side covered and permanently joined with one or more ceramic tiles (11). To simplify the process without sacrificing stability said method comprises the steps of: a) manufacturing one or more green bodies with cavities (12) extending from the surface on one side of said green bodies into the interior of said green bodies and sintering said green bodies to receive one or more ceramic tiles (11) with respective cavities (12); b) arranging said ceramic tiles (11) in a cast mould (17); c) pouring liquid metal into said cast mould (17) at a temperature and pressure that said cavities (12) of said ceramic tiles (11) are filled completely or to a great extent in order to either fabricate said base metal structure or component (19) directly, or least an intermediate metal layer to be joined with said base metal structure or component; and d) after solidification of said poured-in metal taking the resulting metal-ceramic structure with its mechanical interlocks between said ceramic tiles (11) and said base metal structure or component (19), or said intermediate metal layer, out of said cast mould (17).
