摘要： PROBLEM TO BE SOLVED: To provide a method of producing a ceramic matrix composite (CMC) article (10) having a net shape, by which the article can be formed to have an exterior surface (40) with desirable characteristics, such as being free of imprint pattern of fiber reinforcement materials (18, 20) within the article.
SOLUTION: The method comprises a step for providing a body (12) including the fiber reinforcement material (18, 20), and a step for depositing a coating (16) on a surface (14) of the body (12). The coating contains a carbonaceous binder (24) and a slurry containing a ceramic particulate material (26). Following its deposition, the carbonaceous binder (24) within the coating (16) is cured to render the coating (16) machinable, and the coating (16) is then machined to approximately produce the net shape of the article (10).

摘要： PROBLEM TO BE SOLVED: To provide a process for producing silicon-containing ceramic matrix composite (CMC) articles.SOLUTION: A process includes producing a matrix slurry composition that contains at least one resin binder and a SiC powder 24. The SiC powder is a precursor for a SiC matrix of the CMC article and the resin binder is a precursor for a carbon char 30 of the matrix. A fiber reinforcement material is impregnated with the slurry composition to yield a preform 20, which is then heated to form a porous preform that contains the SiC matrix 22 and porosity 26 and to convert the resin binder to the carbon char that is present within the porosity. Melt infiltration of the porosity is then performed with molten silicon or a molten silicon-containing alloy to react the carbon char and form silicon carbide that at least partially fills the porosity within the porous preform. The carbon char constitutes essentially all of the elemental carbon in the porous preform.
