MechanicaJ properties of high performance
ceramics have been improved to the point where their
use in heat engines is possible. The high temperature
strength and low thermal expansion properties of
bigh performance ceramics offer an advantage over
metals in the development of non-water cooling
engine. However, because bard environment in diesel
engine combustion chamber, solving the problem of
durabiUty of TBC is important. DurabiUty of thermal
barrier coatings(TBC) is liınited by two main failure
mechanisms: Therınal expansion nlİsmatch betwcen
bond coat and top coat and bond coat oxidation.
Both of these can cause failure of the ceramic top
coat. Developments of recent years sholv that bond
coats with higher oxidation resistance tend to have
better coating system cyclic lives
