"&lt;p&gt;One reason why cutting tool inserts fail is that microcracks start in the top coating and work down to the substrate, eventually exposing the unprotected substrate to the damaging forces at work during a machining process. Slowing the formation of these microcracks and preventing them from reaching the substrate should therefore increase insert life.&lt;/p&gt;"^^<http://www.w3.org/2001/XMLSchema#string>
