Abstract
Ceramic-on-metal coatings can be made by pyrolyzing pre-ceramic polyme rs. However, the large shrinkage associated with the transformation of the initial polymer into the final ceramic material usually leads to cracks, which develop when the thickness of the coating exceeds a crit ical value. The present work shows that the use of a filler, constitut ed of alumina particulates, allows the critical thickness of SiC-based coatings to be increased by about an order of magnitude.
