Abstract
A ceramic fiber is provided with a plurality of coatings to define a system useful in making composite articles in the manufacture of which the fiber experiences applied stress such as thermal shock. For example, such applied stress occurs in molten metal spraying about fibers to provide a metal matrix composite. The fiber, as a core, is provided with a first coating layer tightly bonded to a lateral surface of the fiber and has a first structure. A second coating layer is then deposited on the first layer and has a second structure different from the first structure thereby defining an interface between the coating layers which is a debonding discontinuity zone sufficiently weak to enable reparation of the layers as a result of applied stress, such as introduced by a thermal shock experience.
