摘要：Mechanical 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 high 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 durability of TBC is important. Durability of thermal barrier coatings(TBC) is limited by two main failure mechanisms: Thermal expansion mismatch between bond coat and top coat and bond coat oxidation. Both of these can cause failure of the ceramic top coat. Developments of recent years show that bond coats with higher oxidation resistance tend to have better coating system cyclic lives.
