Effect of BN interfacial coating on the strength of a silicon carbide/silicon nitride composite
Description
Boron nitride has been identified as a good fiber/matrix interface coating for SiC fibers in a Si3N4 matrix. Boron nitride thin films prepared from BCl3 and NH3 at 1,000 C and from B2H6 and NH3 at 550 C were deposited on SiC (Nicalon) cloth in a low pressure chemical vapor deposition reactor. The coating thickness was varied from 0.1 μm up to 4 μm. Six layers of cloth for each coating thickness were incorporated into a chemical vapor infiltrated matrix of amorphous Si3N4. Flexural strength data and composite toughness were obtained from three-point bend tests. Scanning electron microscopy and metallographic analysis of fracture surface morphology were used to determine the failure mode
