Claims20
A method of correcting a manufactured article, comprising:
- applying a machinable coating to a manufactured ceramic matrix composite article with a manufacturing artifact;
- and
- machining the machinable coating to provide a desired geometry.
A method of correcting a manufactured article, comprising:
- providing a preform of ceramic-based reinforcements held in place in place at least one fixture;
- infiltrating the preform with a ceramic-based matrix to form a manufactured article having at least one manufacturing artifact corresponding to a connection point between the at least one fixture and the preform;
- correcting the manufacturing artifact by applying a machinable coating to the manufactured article.
A corrected article, comprising:
- a manufactured ceramic matrix composite article, the manufactured ceramic matrix composite article having a manufacturing artifact;
- and
- a machinable coating on a surface of the manufactured ceramic matrix composite article correcting the manufacturing artifact such that the manufactured ceramic matrix composite article has a desired geometry.
