Unfortunately, as lacking of sufficient knowledge on UHTCs thermal protection materials, development and application of these materials have been limited.
Current research shows that the poor TSR of ceramic materials is because of their inherent brittleness, thermal shock is the important cause of catastrophic failure of ceramic materials [3,4].
Moreover, known from these four figures if some certain constraints are imposed upon the materials, the materials can withstand the more critical fracture temperature difference.

Besides the wear resistance, high strength and toughness are necessary for mold materials to withstand the loads during application.
This layer additionally to the higher vaporization point of zirconia hinders the machining process of zirconia based materials and therefore lowers the removal rate.

First of all, FSP may change material properties over the thickness and material behavior is the same as functionally graded materials [5-7].
A lot of researchers work on analyzing crack through the functionally graded materials analytically or semi-analytically [8-9].
In the case of the second tool, volume of the materials which undergoes severe plastic deformation increases drastically.
