Abstract

See full text

A fine, hard particulate is distributed within a fused coating on a substrate. The distributed, fine, hard particulate function as crack arresters, so that a propagating crack is actually stopped upon encounter with the hard particle, and enhance nucleation during the coating formation, so that finer grain size is achieved within the coating, which in effect decreases the crack length in the coating.
