Document Type and Number:
Japanese Patent JPH05507317
Kind Code:
A
Abstract:
The present invention relates to a novel process for making a macrocomposite body. Specifically, a metal matrix composite body is first formed and thereafter, a ceramic body or a ceramic matrix composite body is caused to form from at least one surface of the already formed metal matrix composite body. The ceramic or ceramic composite body can be formed by, for example, changing from spontaneous infiltration conditions which permit a molten matrix metal to infiltrate a filler material or preform to conditions which favor the growth of a ceramic oxidation reaction product from the matrix metal (e.g., the matrix metal serves the dual role of a matrix metal and a parent metal for growth of oxidation reaction product). The growth of oxidation reaction product can occur from one or more surfaces of a metal matrix composite body and can be controlled to result in any desired shape. Moreover, the oxidation reaction product can be caused to grow directly into an atmosphere to form a ceramic body or can be caused to grow into an adjacently located filler material to form a ceramic matrix composite body. The oxidation reaction product can be formed substantially immediately after the metal matrix composite body is formed or may be formed at any point later in time.
